I think something along these lines is definitely needed, but I want to
caution against tying it to \n% too strongly -- many macro packages use
their own register(s) and/or string(s) for the page number and
completely ignore \n%, so you need a mechanism that the macro package
can use to communicate the information rather than building something in
to groff that isn't modifiable.
