Hmm, might be a good approach indeed.

RHEL 7.5 release should be around March/2018 but hopefully we can have a
spice-gtk release before that. So if we agree that upstream code to be
compatible with 7.4 and 7.3 till 7.5 is released, this patch should be
postponed indeed.

(I'm glad that I doubled checked for 7.3 glib before bumping it!)
