Nostr solves the account portability, albeit poorly. (Your identity is your public key, so if the key gets compromised your identity is as well)
I am more excited about Takahe, which decouples the servers running the federation from the domains holding the actor ids. This means that a hosting provider like mine won't need to allocate one whole instance for each user that wants to have their own domain.
There is also a FEP from the developer of Mitra which aims to flip the ownership of the account keys, which would prevent cases of servers going under and stopping users from recovering their identity.
