I don't think it really addresses the issue because it still requires an account at one of the predetermined identity providers. With email I just need a domain and I can self host the rest if I really cared to.

It would be so much nicer if there was a federated way where I the user could specify any OAuth identity provider (even if it was e.g. a self hosted one) rather than the predetermined list dictated by the relying party.

Funnily enough someone recently asked me if I could comment on a Product Hunt post and I was unable to do so since they only allow sign in with Google, Twitter, Facebook, Apple or Linked in; I have none of these accounts and would rather not create any of them. Oh well.
