Bruce,

I agree that a registry operator can technically operate a thick and
thin model in parallel, and the choice can be made available to
registrars according to their business model and technical resources.

Jean-Michel,

I agree that less code to maintain = less cost. I think that registrar
selection between two registry-offered models can meet that goal.
