I want Mastodon threads in Lemmy.

Won't come.

Mastodon has no support for enclosed threaded conversations whatsoever. At all. Why not? Because Twitter has never had any either. That's not how microblogging works. And Mastodon tries hard to be minimalist, purist, old-school, original-gangsta, Twitter-like microblogging, just with a few more characters.

Mastodon barely manages to tie its threads together with mentions. But it neither has nor supports nor even only understands the one-post-multiple-comments conversation model.

You even have to jump through hoops both on Mastodon's Web UI and in every single last Mastodon app to see a whole thread. Like, actually the whole thread and not just the branch with the "toot" that you were just looking at.
