I’m really disappointed with Lemmy’s idea of federation: all it is is a bunch of servers mirroring one another, but the user accounts are server-bound. No jumping instance and taking your identity seamlessly with you.
This isn’t really Lemmy’s idea of federation, it’s just ActivityPub, the underlying protocol. Having a mechanism for jumping servers is unfortunately quite complicated and it isn’t clear how it should be done or if it is even possible.
Lemmy does allow you to export and import your settings though, so you can kinda do it but you lose your history.
The problem as I understand it is basically that user IDs in ActivityPub are intrinsically tied to the domain on which the user registered, so you can’t really move a user from one domain to another.
Well no they can’t, because that’s not part of ActivityPub. In fact ActivityPub mandates HTTP URLs. Of course, any extension can choose to change that, but since nobody is actually supporting magnet links, it’s not relevant.
You have a gmail account that is tied to google. You have to login to gmail to access your email but you can email anyone in the world. Some people use different providers so they have different email addresses.
If you want to change providers there is no easy way to do it. You can use imapsync or export to pst and import to new provider and so on, or maybe your new provider gives you tools for importing mail from your old mailbox but it’s not a feature of email protocol(s) to do this.

ActivityPub spec allows content-addressed IDs, just nobody implemented them and now it’s too late.

It’s not true, all ActivityPub IDs are URIs
Yes exactly - those URLs contain the domain name, so you can’t change servers for a user as their ID is tied to the domain.
They can be URNs (like magnet:), as shown above.

There once was a discussion going on to implement DIDs in ActivityPub.
Unfortunately you can’t just change the ID format as it would require a breaking change to the protocol.
pretty much. That’s why the discussion is still on draft.
This is exactly like email though.
