Can you add some comments about what makes these types unique? I know we haven't
done it for the existing types, but its less obvious to me what these are about.

Tried to explain in the enum comment. I don't think it makes sense to explain
individual sources and their specifics here, since they are defined by the
factory and may change.

Acknowledged.
