I don't have a problem with that, but what would be the problem with
supporting both:

  bpftool map dump name pids_filtered

and:

  bpftool map dump pids_filtered

And for that matter, even:

  bpftool map dump id 30

And

  bpftool map dump 30

Ditto for 'pinned'?

I.e. less typing, the tool can be smart enough to figure out what is
that is being asked, i.e. is it a number? Try first it as an 'id', etc.
