I agree that there is some effort but OTOH, it gives the flexibility
to do a focussed review and as soon as some patch is ready or close to
ready we can merge in the main patch. This was just a humble
suggestion based on how this patch was making progress and how it has
helped to keep some parts separate by allowing different people to
work on different parts of the problem.
