Hi,

This should probably rather be discussed at the OpenID :
https://lists.openid.net/mailman/listinfo/openid-specs-ab

Fwiw, I don't understand the "auth secondary 1/N" in the schema, and the
"account resolution".

It looks like you're trying to solve a problem that some RPs might have by
using the email address as an identifier instead of the "sub", so now
there's a need to "migrate" that identifier to another value when the user
changes their email address. But that's a misuse of OIDC by the RP, that
can and should be solved on the RP side.

The email address in OIDC is only that: an information of how to contact
that user by mail, and certainly not an identifier for that user (that's
what the "sub" is for)
