Is there any benefit to it over nostr though? You'd have to link your public key to your account(s) and store a backup of your private key in addition to your regular login/password just to get a more fragmented and less seamless version of nostr. A lot of people already have issues figuring out how fediverse works with multiple instances and all... now they'd have multiple accounts with different credentials to keep track of on top of a meta login/password (pub/priv key). With nostr you only have 1 login/password (pub/priv key) to everything, it's just long and you can't change it. At least I think that's how it works, I don't really use twitter/nostr/mastodon type of sites.
