Requirements to merge new heaps in the kernel

Hi Sumit,
I wanted to follow-up on the discussion we had at Plumbers with John and
T.J. about (among other things) adding new heaps to the kernel.
I'm still interested in merging a carve-out driver[1], since it seems to be
in every vendor BSP and got asked again last week.
I remember from our discussion that for new heap types to be merged, we
needed a kernel use-case. Looking back, I'm not entirely sure how one
can provide that given that heaps are essentially facilities for
user-space.
Am I misremembering or missing something? What are the requirements for
you to consider adding a new heap driver?
Thanks!
Maxime
