I don't think it does, but if it did, we have an answer. Yes, Apple implements ideas they did not originate. Right-click is sort of the canonical example, because they fought it for a long time. Tool Tips is one I wish they hadn't, I hate them. Tabs. Unix. Enterprise management. The command line(!)
I'm not really talking about will apple adopt outside ideas, I mean will apple allow people to change or customize the interface on their own device.
Nope. It's more about educating users about some basic concepts of the OS.
