Hmm, originally I didn't use them because they created a sub-directory,
but I see now that's optional.

Still the input format is completely different and doesn't fit into
the ->attrs list that are used elsewhere (e.g. for the sysdev_classes)
So using groups would need a lot of restructuring.

Also similar code as I have is already in a lot of places, which
over time will be converted. So it's definitely less code than
before.
