@dajb Apparently AT addresses this with some identity layer providing a type of DID enabling nomadic identity. But apparently there are also more backwards compatible (wrt current fediverse) solutions in the works.
@dajb I do worry a bit about the fragility of fediverse identity though. Account migration path cut as soon as old server destructs. Ironically a plausible case for why a user would want to migrate in the first place.
@sef What's AT?
