This isn't possible at the moment.

If you inherit from a Process, you have created a new Process that could be incompatible with the ProcModels of the old Process.

How would the compiler know that you only modified the Proc in a compatible way?

Perhaps we could label the sub class in a way that it is compatible with ProcModels of the nearest super class. But then we've broken the design because Procs shouldn't be aware of their implementation. ProcModels specify which Procs they implement.
