Traditionally we try to not constrain client design more than necessary,
but that doesn't mean we strictly limit ourselves to defining what
happens on the wire.  And to the extent that we have limited ourselves,
if we're learning that this is not sufficient, that's a good reason for
relaxing that limitation.

IMHO it would be reasonable to define a profile of HTTP for use with
interactive web browsers.

I don't see why we shouldn't describe these things if doing so helps
acceptance and interoperability.  Perhaps as informational rather than
normative text, but we should make sure that there's a complete
picture.  These things are important to the success of an authentication
system.  A lot of our failings in the area of authentication have been
due to failure to consider more than just the on-the-wire protocol - we
haven't tried very hard to make our technology accessible to potential
users.
