Why can't we leverage existing conventions here and say that the default behavior of the axes is to pull a single level, and then if a modifier is present, e.g. s1 / *types or s1 /*supertypes, then we pull the whole thing.

I could live with your last proposal as well. It's a tough call to decide which i like better. Probably a draw. I think most importantly the default should be the same over those four.
