Yes, for self-hosters we are working on including Discourse ID as an easy option for the initial setup. We’d like to see if it can let people start a new instance without the dreaded email step, because with Discourse ID, users don’t need email for setting up their first account. They will need email eventually, but postponing that arduous process even a little bit is useful.
We are also looking to enabling Discourse ID by default on signups in our hosting.
