Something I've done in openSUSE and Mageia that might be worth doing
in Fedora is a namespaced glob, where the somajor is specified and the
sublevels are globbed.

You can see an example of this with my fdk-aac-free package in
openSUSE here: https://code.opensuse.org/package/fdk-aac-free/blob/4d35a883c89e7569349fc21664d8c5d1a2de6328/f/fdk-aac-free.spec#_87

Admittedly, it's a lot easier for me to do it this way in openSUSE and
Mageia rather than Fedora since I also need to name the library
packages with the somajor in them...
