But in the end it doesn't matter, the server sends the appropriate
challange (assuming acceptable credentials weren't in the request)
and the challange is either understood or it isn't. The outcome
is essentially identical ... the request is authenticated or it isn't.

Yes, it takes an extra set of round trips as the server can't reject
the request out of hand. In terms of %age of total http network traffic,
it will be lost in the noise.
