@arcanicanis @AlgorithmWolf @Flaky >Seeing all the responses to a post, versus the present ‘split-brain’ post discoverability: there’s an architectural reason that even if you have the server of the parent post track all the responses, that you couldn’t just have a remote server pull all the responses. Because even if the parent server lists all the known responses to a post (local and remote), that there’s no proof of authenticity for remote posts, thus every single remote reply would have to be re-queried. Think of hellthreads, and a sudden flood of +500 queries from just one server querying a thread, that’s obviously a bad idea.

The problem with that is, it violates privacy according to the Signed/Authorized Fetch cartel. Unless you're willing to do what @mint does with a bunch of clever tricks for working around that, you're going to see the very real problem of "half the posts don't show up".

Furthermore, Akkoma has it on by default, GoToSocial forces it IIRC, and anyone who runs those two stacks has issues federating which means that others are basically strong armed into implementing it because otherwise you'll find bugs like "THIS WON'T FEDERATE", etc.

There are a lot of people who will break federation to chase the dragon of "nobody I don't like on my network", which Bluesky comes the closest to by being not that different from say Cohost as it is now.
