Once you have this, you might as well make that granularity per VMA.
This gives you the advantage of being able to share the mapping for libc.so ;)
From what I can see, you'll basically want large pages for:
1) Oracle and maybe other large shared memory situations where the page table overhead would otherwise be prohibitively high
2) scientific calculations and other programs with a huge dataset where TLB misses would be prohibitively slow
