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 my understanding is that mastodon is incapable of this on an architectural level and that the project's leadership doesn't give even a single shit about it.
hope you don't get too many "ah but post history doesn't matter, why do you care anyway, it was never intended to be permanent, you should just embrace the impermanence" etc etc replies to this.
@jplebreton I would simply change the architecture
@mcc totally a thing that projects can decide to do, communicate about, and gradually implement, if they know what they're doing!
