Does that at least cause a rebuild if the linux-headers-* package gets
updated? IIRC as long as KVERS does not change, dkms does not rebuild
modules on header change.
More general: if linux-headers-* gets updated but the ABI does not
change (and the ABI is not 0), does dkms have to rebuild the modules? Why?
If the ABI changes, the package gets renamed and the new installation
implies a rebuild.
If the ABI is 0, this should be treated a non-stable ABI and an update
of the header package should definitively trigger a module rebuild.

So that flag is not doing what you expected. And I think on Debian it is
ignored and we always build for all kernels. But only on new header
installation or on dkms module update. Not on header update.
