I understand your concerns about adding possibly frivolous interfaces

Does it help we export the phys_index (basically the section number) as
part of the section directory?

I don't think we export the physical memory ranges of NUMA nodes. But,
if we did that as well, it would allow userspace to do this association
without troubling the kernel with maintaining it.
