I guess i butchered my complaint. I was thinking of migrating accounts or one account for all instances or something like that. Multiple signups are still a bitcannoying. Although it only matters for defederation corner cases and instances closing up.

Ok i butchered it.

I was thinking of federated accounts, not participating in posts across the fediverse.

when you want to migrate instances, its annoying to create the same account name again and again.
