What is mostly of interest to me if when they're used only by
dpkg-gencontrol, _when_ they are added doesn't matter, and it looks like the
place for checking would be here, as dpkg-gencontrol is THE one (apart from
his caller, which may vary) which knows for sure what its arguments are.
Maybe in the default dpkg-gencontrol behaviour (reading from
debian/substvars) it is not expected that all vars are used, but
dh_gencontrol uses separated substvars files for each binary package, and
calls dpkg-gencontrol with -T. In this case we know for sure that all vars
in THIS file are intended for THIS package, and we can warn. Or do I miss

I'm not sure it's the most effective way not to get ideas lost, but well...
