I'd rather plugin generated code that applies general rules to the transitive closure of all types needed. The markings would be for exceptions to those rules, which should be very, very rare. The load for someone writing and maintaining code is then reduced and the fear of GTY doesn't play a role in activities such as refactoring, as there would be nothing to do. I know it, and I have a healthy fear of it. :-)
