And I find the advice on emacs problematic as well and make things complicated for users. In the case of python, final packages should not wear a pyXXX prefix, so during upgrades for users pkg upgrade will just propose to install the new set of dependencies which will conflicts with the old one and as such propose to remove them. (this is not done in the python world, at least not always and causes tons of problems). I am not an emacs user so I don't know what have been done there and can't argue. In any case the pkg set was a transition tool to cope with areas where we have "weak" packaging rules, which means each time pkg set is necessary we have to think how we can fix our packaging rules instead.
