you could, but there are plenty of cases (the roaming user) where there is
no need. Those of us advocating the disassociation are not saying 100%
disassociate. We are saying make the base-line MUST disassociation, but
allow the user's the ability in configuration to associate and look for ID
in a certain place in the cert IF THEY WANT. That way, the 10% of the cert
users that want to associate will get what they need, and the rest of the
90% will have something that works easily. 

This is the basic convenience vs. security continuum. Our job as protocol
designers is to give the people something they can use. 20% want it super
secure at the cost of convenience. 80% want it secure, but convenient, and
are willing to make the trade-off from the super-secure. The text I proposed
tried to reach this goal.
