I came here to say this. It should really be an opt-in behavior rather than opt-out. It's not the only reason chrome has become a not-so-good citizen on macOS: the memory/CPU footprint is bad enough, but it also does things like give system-like popups when a new printer is detected on my network. I'm not sure when I permitted chrome to do this, and it seems like it's trying to subsume more and more of my system's function without asking. I find the command + q thing to be a particularly annoying version of this.
