I believe thunderbird has support for Gemini but I haven’t tried that out yet, might be wrong.
I think it depends. Not entirely sure though. Now given the context of Lemmy right, you can certainly post to instance C from both A and B. Even if your instance (either A or B) will not fetch messages from each other (due to not federating) you can always go see the messages through instance C (not logged in). That probably works for all defederation scenarios but that is also a very loosely defined interaction as both parties will have to do the same.
A diplomatic answer I know.
It’s the ActivityPub API (client to server) where clients supposed to interface with so that you could have one client, for all fedi. But turns out server implementations (Lemmy, mastodon etc) find it not so well designed or performant or adequate (or idk what else) so instead they implement their own client APIs, effectively making clients being specific to the server rather than interoperable (one client that could understand all servers). It’s reasonable though, it’s just … I thought… that this was already done and established… but well…
Don’t like leaving anything to the imagination, right?
This captures exactly my inner feeling regarding the fact that no fedi servers implement the C2S api … (I just realised)
But really, this is very well done, thanks for sharing
