I think it would be really great if you can write down a list of the
things you actually want to accomplish. Dare I say: you need a
requirements list.

The numa_vamaps approach continues down the path of an ever-growing list
of highly-specialized /proc/<pid> files. I don't think that is
sustainable, even if it has been our trajectory for many years.

Pagemap wasn't exactly a shining example of us getting new ABIs right,
but it sounds like something along those is what we need.
