It shouldn't ... we created that option on ppc originally to avoid allocation/reallocation of resources. If they are bad, leave them bad, but it was never a question of disabling all these other things.
(Ok, the MRSS/MPS is debatable, but why not plumb the parent pointers and why not claim ? That doesn't make sense to me).
