re the first bullet, out of curiosity, were there some recent decisions by Fandom that caused controversy here which spurred this desire to relocate?

Moving would not be required to end the "message wall" feature, admins are able to switch that back to standard "talk page" format at any time, AFAIK

Same thing with comments. All possible under Special:WikiFeatures to replace them with talk pages.
