Plus if the patches get applied it at least makes it easier for people
who do decide to do such major surgery.

Indeed, part of the reason I was asking about the split was to help me
figure out what takes the place of constraints - sounds like nothing?  I
wonder if we could have cards support this by providing fixed
configurations that we could check against using less code or something.
But like you say, we *must* have some other room for improvement.
