Makes sense to me - I feel similar. But I needed to ask, because one
of the core developers was a huge fan of Cayenne in the past ;-)

Cayenne PMC will need to vote on DirectMemory releases. This doesn't make m=
uch sense with the current PMC composition (we have no people involved in D=
irectMemory development on the current PMC). If we vote in DirectMemory fol=
ks to the Cayenne PMC, and they will vote on DirectMemory releases, while w=
e'll vote on Cayenne releases, we still don't have a cohesive PMC, and ther=
e's no reason why DirectMemory can't be a TLP in that later case anyways.
