Lemmy doesn't, since it's not part of the protocol, and in both situations you still lose your actual id.
In general, there's technical reasons why ids and instances are associated on Lemmy / Mastodon, but not UX reasons.
99% of users just want a username, i.e. @bigCommieMouth, they don't necessarily want their identity tied together with the server they use to interact with the network, i.e. @bigCommieMouth@kolektiva.social, and if they did really love a specific server and wanted their identity tied to it, they could always just make @bigCommieMouth_kolektiva_social.
So? 100% of users never used the fediverse before it existed. Bluesky / ATProtocol is now offering an alternative where usernames are not tied to instances, and that sounds like a better UX.
i thought this thread was about me correcting misunderstandings about activitypub software. i have no interest in bluesky until/unless they either aferro gpl their code or implement activitypub federation. there are no merits to their network that i can see unless one or both of those come to pass.

I don't see a title saying "self post: let me correct you about the activitypub protocol", I see a link to Bluesky launching federated storage.

Then don't engage in a discussion about their identity system, just post a blanket comment saying "they suck cause they're not open enough" and leave the thread. The rest of us are here discussing the relative merits of one protocol vs another.
