The number of people who are going to have this problem should be
tiny, as oyranos isn't actually required by anything in Fedora except
cinepaint and icc_examin, but colord is a hard dep of about 5 or 6
core packages in Fedora.

I could add a "Conflicts: oyranos" to the colord spec file, but that's
not terrifically nice, as you'd then have to remove most of GNOME and
CUPS to install oyranos. Given that colord will pretty much always
exist, it makes more sense for oyranos to disable devices in colord
rather than the other way around. I've shown Kai-Uwe how to do this
just now on IRC, but it's pretty much just calling ProfileInhibit on
each device in colord that oyranos wants to manage instead.

I think my standard answer here is
