I think I've said it before (?) but there is a issue with allowing title edits on older threads that would make the user experience worse on here, more than allowing it.

Why not just have a generic thread title, or have a part 2, 3 etc. or a 2020 version of thread?

Sometimes when a thread title is edited to something completely new it causes some confusion because the earlier posts don't correspond to the title.
