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.
