on the contrary, you are asking some excellent questions. this is precisely what I need as input, feedback, etc. to answer some of your questions below, right off the cuff:
(1) we would need to determine how it exists alongside other efforts that are meant to centralize community-facing notices (like the Diff calendar, or this forum).
*Possible answer: that is a good point, however the fact that the need exists at all already identifies the niche for this effort, and the need for it.
one answer to your question is to look at the need specifically at it exists at the specific plat form that we are looking at, which in this case is English-language Wikipedia. in my opinion the answer is that there is almost no community-based group or effort designed to keep the liaison with WMF, and to address Wikipedia governance processes in general, not to mention, no platform to represent the community concerns, ideas, questions, or areas of cooperation that can be carved out in regards to WMF. I would like to carve one out, little by little.
Furthermore, Wikipedia is sorely in need of a platform/space/project in general which will greatly increase and foster the dynamic of community collaboration. it might seem like that’s what we are all about already; however that is not the case. the current trend towards local meetups who hold their meetings via zoom, illustrates a vast new potential area waiting to be tapped. we should be having zoom meetings for the editing community based around topic, not just around region. remember that my own role hinges upon WikiProject History, where I am the Lead Coordinator. I would like to work with one or two other people, and start developing a collaborative model and group communication process around this topical area.
As part of the last item above, I feel that we need an inter- WikiProject task force which would span several WikiProjects. each task force would be focused on one topical area. for example, I envision a task force based at WikiProject History, which would enlist reps and liaisons from several wikiprojects related to history, who could exchange ideas and information to promote greater community involvement. currently, there is nothing to draw an ordinary editor towards the WikiProject where activity is greatest, unless they specifically find it on their own. I would like to create some kind of inter-project task force/conduit/ collaboration. there would be one for each topical area. I would create one for history. there would be one for science, math, etc. I would also be willing to create one for politics, but only once the one for history has achieved stability.
furthermore, we need a wiki meetup for the USA as a whole. we currently have other meetups for entire countries; the USA is one of the few that does not have one. the reason is the highly active local meetups which already exist for the USA, which are highly exemplary local chapters. however one problem with them is that they are not available to hold regular meetings when requested to do so. the USA meetup would serve as a general resource for all interested editors, on a continuous basis; not just when some of the group moderators choose to hold meetings.
I realize I have gone a bit far afield, but all of this fits closely together. the next big direction for Wikipedia is to create whole new methods areas, and resources for greater open-ended collaboration. my core goal in joining this forum is to advocate for and foster ways to do so. we have the means to chart the course that will carry Wikipedia through the 21st century, and into future centuries. the time to act is now.
(2)Another question for me would be: who is responsible for posting all the relevant information - how do we prevent it becoming just another site that I need to copy & paste information to because I need to make sure I’m hitting as many people as possible across all the different spaces, platforms, sites that diverse groups use?
I understand; however, remember that on all the existing platforms, Admin Noticeboards, Village Pump, Teahouse, etc., there is little or no current updated body of data documenting all the governance processes currently in motion. we desperately need this at Wikipedia. I would like to move forward with this forthwith. to do so, I need the support of at least one highly-credible, well-respected editor with knowledge of WMF. I could greatly use your help in that respect.
furthermore, I have a new unprecedented idea which might help us to achieve this mission.
how about a Navbox with a chronological basis? in other words, we would create a Navbox called “2020s WMF process.” we would make it decade-based, because decade are the building block for chronology at Wikipedia. but furthermore, we don’t currently have any genre of navboxes which focus upon current updates relating to Wikipedia for a specific time period.
if we create this, that would be one step along the road to create a clear, approachable, and convenient resource for the community as a whole,. to bridge the gap between WMF processes and the editing community as a whole, and also to bring the editing community into contact with WMF in a way that would be positive, beneficial, and conducive to positive collaboration, for the benefit of both sides.
ok, that is a whole lot of typing! 
what do you think? if possible, I picture moving ahead with you forthwith. by charting a course together, and then transferring our efforts to English Wikipedia, to start building on our ideas and efforts there. Nothing needs to happen right away; that is simply the overall oal that I picture down the road sometime, but nothing needs to happen on an immediate basis. what’s your thought? please feel free to let me know, @FPutz_WMF . thanks!
