So, the idea I had is that for things like this:

- you subscribe your multi-arch system to both channels

- the decision for what is installed is done via yum plugins/configurable
  yum behavior
  
You could say 'multlib=devel', to get development packages and their
dependencies. Or 'runtime', to get runtime libraries. Or 'none', to
get, well, nothing.

This isn't something that can be done for F7, though.
