Danny,

First I think the little change below can not be compared to the serious
of proposals made in the "... numerous layer violations... " thread a
while back. You are just not comparing the same orders of magnitudes
here at all.

Second I always thought that the nature of a draft is to be able to
adjust it to fit it to the most of the operational community or proven
solutions. That is not to say that the nature of the draft allows to
turn it upside down while it is in the rfc editor queue and deployed
widely :).
