I'm not sure what mgorny has in mind, but the problem I see with saying 
I want just X to be my provider system wide is that some pkgs build with 
X others don't, other pkgs might need a different provider.  So it might 
make sense to order them in terms of preference: X1 > X2 > X3 ... and 
then when emerging a package, the first provider in the preference list 
that works is pulled in for that package.
