The maven version is exposed to the outside world, not much today, only 
that the POM files are published in every installation done in Fedora. 
And it will be much more exposed in the future, when other people starts 
to develop components based in our (yet to be created) plugin 
infrastructure. So it can't be 0.0.0 for all versions.

This patch didn't create any relation between maven and packaging 
version, it was already there, and I think is reasonable to have it (to 
the extent that packaging systems allow). So if a decision is made to 
release 3.3.0-beta2, for example, the corresponding branch should have a 
patch to change the maven version to 3.3.0-beta2, and the packaging 
version to 3.3.0-beta2 as well.

What do you mean by "published snapshots"? As far as I know we don't 
publish maven artifacts to any public repository at the moment. Or do 
you mean nightly builds?
