I am quite in favor of using operating-system transformations rather
than inheritance, because they're composable!  This could be leveraged
to get a nice CLI API as well.

By this, do you mean that there's no way with your syntax to modify a
given service?  Is there a reason for this?  It does seem to me that it
could probably be done.
