One possible benefit to trying to deal with these is to synchronize
version jumps; historically, in one instance GNOME and KDE moved to a
newer libpng at different times, and that caused a fair bit of mess
for Linux distributions (and ABI incompatibility across
distributions). So if we coordinated the libpng upgrade as part of a
"desktop platform release" I can see it helping with that scenario.

Not sure this outweighs the downsides - in particular, I'm not sure we
should include things in a release unless they are actually maintained
on, some feeling we should point people to the
official download sites for these things.
