> I think Apple did the right thing by keeping GUI shortcuts separate from terminal control codes

They are separate because they ditched terminal shortcuts and later begrudgingly brought them back. The original Mac didn’t have a control key. They added it back in 1987 because of pressure of terminal emulator programs.

You mean they successfully resisted the temptation to repurpose Ctrl, even though they were sure never to need it again. They did the right thing by introducing a new key for a new thing.
