I might as well chime in on the actual question that was asked. I guess I disagree with the majority of folks working in the sub-IP area. I never thought it made any sense to move all those working groups out of their original areas into a "sub-IP" area, and I never understood the "sub-IP area hourglass architecture" that was foisted on us by the IESG. So I've never thought that it makes much sense to have a separate "sub-IP" area, and I don't think it makes sense to keep it as a separate area in the future. The advantage of maintaining the status quo is that everyone has gotten used to the current ADs, and most people figure that any change will make things worse. When new ADs get involved, they tend to "reinterpret" the charters and disrupt the work. But if one ignores the possibility of short-term personality issues, I think it would be better to choose established areas for the MPLS, CCAMP, and PPVPN WGs.
