Apple is quite happy to patch & extend stuff. Their ssh-add(1) accepts --apple-use-keychain, --apple-load-keychain; vanilla OpenSSH doesn't even know what long flags are. I think it's entirely OK for long-established programs to adhere to their conventions; it's less surprising for the users. If you're going to change how things work, do so with minimum impact on the UI. (I wish their GUI teams understood that.)
