i'd advocate impressing on the functional groupings the need for oversight.
But, that oversight is *only* the responsibility of the PMC. If it's the functional groupings, then those should be top-level projects themselves and PMCs in their own right. If a 'functional grouping' is large enough to manage itself, then it should be a TLP.
more liberal policies than httpd. IMHO it would be easier to increase the membership of the jakarta pmc to more acceptable levels if we'd previously asked senior committers to provide a secondary level of oversight. (of course, the responsibility would rest with the board.)
Those 'senior' committers would be the PMC members. -- justin
