If we start to convert modules, but don't complete, then python3 will
be forced onto live cds, in addition to python2. Looking at the
python3 and python3-libs packages here, that looks to be on the order
of 25-30M. Not the end of the world, but some extra space to save
somewhere else. The bigger issue is probably with support libraries
and plugins; it will get more messy than it already is. Eg:

rpm -qi pygobject2
...
The pygobject2 package provides a convenient wrapper for the GObject library
for use in Python programs.

rpm -qi pygobject3
...
The pygobject3 package provides a convenient wrapper for the GObject library
for use in Python programs.

Yet, both depend on python2.7 ???
