really into this idea, it does raise questions with identity as you say. why not make it more explicit than a repository at a different level than instance identity? eg. a link between accounts across instances in the same way the rel="me" links work in account metadata. identities indicate which pixelfed identities are theirs in some publicly indexable way, so if someone is trying to use it for abuse by eg. signing in across hundreds of pixelfed instances it would be very visible and moderatable.

or, I guess as a question, why as a centralized repository rather than as account-level metadata?
