Yes. But today I'm going to made some changes, based on my experience
playing with this code last night. In particular, it should be possible
to have *only* the named rules be customization points; for all other
rules, actions are attached to rules the old way via proto::when. I
think that if we pass the Actions bundle as the Data parameter to the
transforms, these things become possible.
