Thoughts on PackageKit being a hard-dependency

[Rex Dieter]

Per, "phonon dependencies prevent running a reasonable Fedora without 
PackageKit", https://bugzilla.redhat.com/show_bug.cgi?id=694169 there 
currently is a hard
Requires: PackageKit-gstreamer-plugin
in phonon-backend-gstreamer.

The original rationale included:
1.  ensure the gstreamer install-codecs-on-demand feature "just worked"
2.  avoid phonon crashes when the pk-plugin was not present

Turns out, the crasher bug (2) has been fixed in phonon since.  phonon 
upstream continues to recommend the dependency (1) for usability reasons.

Now, we could try to pull in PackageKit-gstreamer-plugin by other means 
(like comps), to avoid the hard dependency, and satisfy the reporter 
(and supporters) of bug #694169.

Looks like Kevin prefers to keep the dep.  I'll continue to have a 
slight preference to defer to upstream's wishes to keep the dep.

Any other opinions?  What say you?
