OK, but if your package manager can handle the incompatible case, it 
also won't surprise you when repo X updates their compatible but not 
fully functional version before repo Y does.

If the packages and all included files can be named differently, they 
could simply co-exist, but that doesn't always work.

But it would be even better if we could live with the assumption that 
repos will have incompatibilities, whether accidental or intentional. 
Then it would become a choice of which to install and things wouldn't 
break when somewhere else updates first.  Then you could focus on making 
your versions better instead of compatible - and the politics wouldn't 
matter.
