Today it works kind of similar to e-mail (except there's some notion in servers for migration), so yes, you'd generally get a new public identifier as you move servers. So server admins do have a lot of practical authority in that sense. It's a tricky one to solve properly (see Zooko's Triangle). The only solutions I've seen so far rely on distributed ledgers, to which there is cultural resistance. We do need to arrive at a DiD solution, though. Matrix needs to solve the same issue, so ideally we'll find something that works in general. Perhaps the W3C proposal is viable. Devs and admins in the ecosystem realize this and other ways that the current state of ActivityPub is not ideal. If you're interested in following discussions on how to improve and evolve the Fediverse protocols and ecosystem, some people are congregating here (and yeah, we should dogfood better). https://pad.public.cat/8yNgnlxmSsGYk3TfIau46A?view https://pad.public.cat/8yNgnlxmSsGYk3TfIau46A?view #socialcoding-foundations:matrix.org https://codeberg.org/fediverse https://codeberg.org/fediverse
