@MRJames2017 I have mentioned the two questions in CURED: chat.stackexchange.com/transcript/2165/2021/9/17 (That's probably a more suitable room. In any case, some people will see your message here and some in the other room.)
Just mentioning that our Do we want accepted answers unpinned on Math.SE? thread had more than 1000 views, and about 100 votes were cast. That is a good participation, I would say, and (as far as I can see) more than for most (if not all) of the corresponding discussions on other sites.
Interestingly, our friends at Math Overflow did not discuss this at all, at least I cannot see it on their Meta. Perhaps it was discussed in one of their chat rooms?
