I'm unconvinced that Conflicts does anything useful at all.  It's 
obvious that installing two packages with the same module name is a 
conflict (probably an upgrade).  Anything else couldn't possibly 
conflict in any concrete way in the same way that Provides and Requires 
can't mean anything useful without specifying actual module names.  I 
say get rid of Conflicts altogether.
