I can't think of anything except compression that could be interesting
at that early stage, so I'm not seeing a reason to invent a general
negotiation mechanism.  Even if we thought we needed one, we don't have
a lot of flexibility at that stage of the game, because neither side yet
knows what version the other is, and so assuming that the other side
knows of the mechanism is bogus.  The existing method for requesting SSL
is a tad klugy, granted, but I'm not sure we can do any better for
transport-option negotiation.
