And why can't all this be done with s/git/SVN/? All we really need apart 
from what CVS already provides is atomic commit IDs, to make the 
"maintainers would not tag themselves" part easily implementable. I don't 
see why SVN revision IDs wouldn't be as good as git hashsums for that.

In fact, in principle, it could even be done with CVS, but instead of 
tagging a single revision ID, the build system would have to tag the 
revision ID it checked out for each file. Having atomic commits just allows 
dragging around just one revision ID instead of a set of IDs.
