I would change that third sentence to : "You can demand that your macro *is* the interface, but that implies you require your clients to re-assemble their code whenever they want to utilize any of the *real* interface changes"
Any interface worth its salt would support previously assembled code that is ignorant of the new parameter list bits and bytes.

Macros are ephemeral, merely a convenience. You can demand that your macro *is* the interface, but that implies you require your clients to re-assemble their code whenever the *real* interface changes. Not so good from a customer-service (or profit-making) perspective. Some macros are more convenient for my purposes than others.
