The biggest thing missing from Mastodon remains the ability to *actually* migrate an account between servers.

The follower-migrate feature is not enough. I need to be able to migrate an entire account, including posts. And I should be able to do it without the former server cooperating (because of course servers can go down). I should be able to get some sort of cryptographic cert I can send to a new server with my posts and they'll be like "oh yeah, this is real, migrating u now".

@mcc Strong agreement. Personally I think beyond that there needs to be some kind of ID delegation (for folks who want it). I have a domain name which I've used since 1995... I'd like to be able to easily setup some kind of proof that maps my identity tied to the domain I control to some server hosting my account. That combined with actual working migration would let me hop servers if I want or need to *and* have a persistent identity that's human-comprehensible.
