That sounds like the right thing to do. Could be as simple as this.
With this patch:

- An ordinary build of an experimental kernel with "debian/rules
binary" does not build kernel-headers packages.

- However, the headers are still advertised in debian/control and one
can force headers to be built with a command like

fakeroot debian/rules DEBIAN_KERNEL_HEADERS=YesPlease

or

fakeroot make -f debian/rules.gen
binary-arch_amd64_none_real DEBIAN_KERNEL_HEADERS=Yep

Just a sketch, untested. Sane?
