Adding Obsoletes to generated -debuginfo packages ?

In libvirt we recently deleted a driver for the legacy Xen toolstack. This was shipped in a libvirt-daemon-driver-xen RPM. I am able to add an "Obsoletes: libvirt-daemon-driver-xen < 4.3.0" line to the libvirt-daemon-driver-libxl RPM, which gives clean upgrade path for users. If they have the libvirt-daemon-driver-xen-debuginfo RPM installed though that still breaks the upgrade. How can I get the auto-generated libvirt-daemon-driver-libxl-debuginfo RPM to have an "Obsoletes: libvirt-daemon-driver-xen-debuginfo < 4.3.0" statement ? It seems impossible, meaning users with debuginfo have a broken upgrade path. An unfortunate consequence of switching to seprate -debuginfo per sub-RPM.
