Being the development section of the board, I've always been of the preference of this section being strictly segregated to development discussion.
Ideally, I think the initial revival post is not suited to this thread. It's a general (non-developmental) discussion post tethered to this thread by the word temperature.
There has been a clear push by the userbase asking to be careful with stifling discussion, and given the current climate of ML, especially the development of the project, this needs to be respected. Discussion needs to take precedence over procedure.
IMO, the forum police comment is valid. There is a process in place to report concerns to mods.
