This a different discussion and imo not everything can be achieved at the same time. Maybe we should start first by fixing them, then go for the next step anyway. So the transition could be incremental in servers and frameworks and actually fix the current spec. For A (And C), i think we should keep the new specification enough agnostic. Especially since HTTP 2 is not yet completely out. - benoit I
