Yeah, I know it's an unrealistic idea. Just trying to spout some off to 
try and spur better ones.

I'd considered only the distfiles in manifests. There will still be a 
conflict every time there is a newer version in one branch (say an 
overlay, where the files are copied directly across and one bump is 
made) and older versions are deleted in the other branch (during a 
typical tree cleanup), right?
