But, Patrik, doesn't "Expert Review" eliminate the IETF Last
Call that you have suggested (I think persuasively) we should
require until we get some experience.   I agree that having
someone with responsibility to create an initial list is wise,
but that can be done simply by requiring posting of an I-D,
etc., that is a normal first step in the IETF Review process.
