I don't like the author's solution either. Cmd+Option Q seems like an unused alternative that wouldn't require a major re-wire of habits to change to, just a slight mash of the keys to the left.

I initially thought Cmd+Shift Q would be better, but that is tied to System Logout.

Ah, that must be why there's the inconsistency between Mac and other platforms here. On Windows and Linux, Ctrl-Q does nothing; Ctrl-Shift-Q exits Chrome.
