It has been 5 days since the fix, and we have had positive confirmation
that COPR rawhide builds are proceeding [1].

I've filed the F22 bug to do the backport [2].

Given the internal testing we've done with the patch, and the Fedora
Rawhide shakeout, and the desire to improve the cloud/container image
sizes, I'm strongly proposing we commit this change for the Beta freeze.

As discussed the change has no impact on code, it's entirely a packaging
change, which carries it's own risks, but the same kind of risks as a
runtime change. Only users running with kickstart --instLangs or setting
%_install_langs are going to see any difference.

Cheers,
Carlos.
