"#Threadiverse" - nice term. :)
On the technical side: I'm doing this toot from the Mastodon side. I used
https://MYINSTANCE/authorize\_interaction?uri=LEMMYCOMMENTURL
where MYINSTANCE is the instance I'm on (https://framapiaf.org) and LEMMYCOMMENTURL is the comment I chose to reply to (https://lemmy.blahaj.zone/comment/90402).
If I understand federation correctly, my reply should/could turn up on the lemmy instances involved in the thread - even though I don't have a lemmy account.
@sugar_in_your_tea As a non-lemmy-dev, I don't get to participate in that decision either, no matter how strong I think the arguments are.
I'm not convinced that the difficulty in switching is low; as you say, bug/issue tracking is a big barrier, but other features are part of the #EEE strategy [4], and switching later when MS upsets the community like Musk or Huffman will be difficult.
An official mirror would be a good start to make a future move easier.
