I think it is worth it, based on the fact that we get reasonably
frequent bug reports that installing libvirt did not install qemu-kvm,
or similar. Also, it avoids the need for applications to care about
the different package names - eg in RHEL-5 the RPM was 'kvm', while
in RHEL-6, the RPM was 'qemu-kvm', and who knows if it will change
again...
