Are quit() and logout() now protected?

[ceylina]

As of 7.3.2, the functions logout() and quit() are somehow considered protected now. I am trying to look to see if anything has changed that no longer allows you to programmatically call logout or quit() or if there is a new function call that replaces it with the latest patch.

This is what happens when trying to call it.
[ADDON_ACTION_FORBIDDEN] AddOn 'quickQuit' tried to call the protected function 'Quit()'.

I mean I can hit escape and use the built in exit buttons so that isn't being tainted or anything.
