I think you'll restart the 1.2.3.4 versioning is better 'debate' again!

Surly if things are being pushed into a .deb or .rpm we should be using
a real release version.  We should be tagging that.  If the project is
not providing release number, there is nothing stopping you from tagging
them yourself in your copy of the repository and using your tag.  you
could use like 'unofficial-N' where N increments in the way you want.
