It hasn’t always been like this.  We added a feature to anticipate
conflicts that would happen at the time a profile is built.  This
feature now prevents you from installing variants of the same package
into the same profile — this is what we want.  Python 2 and 3 are not
variants of the same package, so preventing their installation into the
same profile is a bug introduced by that new feature.

My proposal would require very little effort to implement.  It is just a
question of whether there is a more elegant approach.
