This uses the new request_module_cap() facility to directly propagate

This is the kind of complexity that I wonder if it's worth it at all.

Nobody sane actually uses those stupid capability bits. Have you ever

They were a mistake, and we should never have done them - another case
of security people who think that complexity == security, when in
reality nobody actually wants the complexity or is willing to set it
up and manage it.
