As much as I hate to agree with Microsoft on any point, I think this
is reasonable. Barring explicit configuration, a client should indeed
select a crypted algorithm (better from its point of view) over a
non crypted one if it's given the choice!

It's the PPP protocol that would have needed a different design, i.e.
some LCP parameters getting negociated after the username is known,
not before.
