The nodejs(XY)-devel packages are not designed to be installed in parallel; however, they are lacking the Conflicts: declaration to make this explicit.

The experimental -bin packages suffer from similar problem, and we should probably come up with a way to specify this sort of thing in a sane way than to just list all the other streams (and then forgetting to update the lists once a new stream is introduced).

This epic is created so that the changes are propagated to all the -devel packages as well.
