What my protocol change proposal[1] amounts to is making the IdP do
the work, which does change this aspect of delegation. It doesn't
change the "portability" of identifiers. In fact, it's a seamless
transition from the perspective of users, unless their IdP sucks.
Because OpenID is decentralized, if you're using delegation, you can
choose an IdP that doesn't suck (for whatever your definition of suck
is), so I don't think it's a real issue.
