There's nothing wrong with that. It's just that the builtin set type
supports that too.

I thought more about iterAtomsForPackage, which is used in lots of
places in the resolver.

The comment was about the fact that you're using a more complicated
selfmade class instead of a builtin type, even if the builtin type would
suffice. The comment made more sense when I was still suggesting to not
use PackageSystemSet at all.
