Nobody working on the problem has suggested that as a requirement, that's my point. It sounds fairly bad in the scenarios that I can imagine using the extension. It doesn't fit the discovery case at all that I can see, and as somebody that runs an IdP, there's no way I would ever allow such a thing on my login page.
