--- Comment #4 from Raphael Groner projects.rg@smart.ms --- It's a common convention to suffix Qt packages with the main version they're built for, see other packages as samples. Only sub packages of main Qt4 and Qt5 packages use it as prefix. Besides that, I'm thinking about skipping Qt4 at all cause its further upstream development is stalled.
Further unbundling of qspicewidget shouldn't be a big issue. We'll see how good Qt5.5.1 (as now in rawhide) works with qt-virt-manager.
It's no problem to have a package that's under heavy upstream development, therefore Fedora is designed, so we're able to do some beta testing.
