When we released post editing for #Mastodon, we first released a version that supported processing and displaying edits incoming from other servers, before releasing a version that flipped a switch allowing anyone to make edits. We're taking an identical approach with quote posts, as the upcoming 4.4 version of Mastodon will begin displaying quote posts from other servers and software. Once this is widely deployed on the network, 4.5 will bring the long awaited ability to quote posts.
I know, it was a tough choice to change something that was kind of part of Mastodon's original concept and even tougher, to implement it in a responsible and fair way, but yes:
I am very sure, it will improve the platform a lot.
Thanks for all the work and especially for changing your mind (I know, how hard that can be)!
