Somewhat related: The last version of Chromium said "Press Alt+F and then X" instead of Ctrl-Shift-Q when I tried to quit it using that key combo.

Unfortunately, Alt+F is trivially overridable by web pages (Twitch.tv in this case -- to move to the search bar), so that doesn't really work.

Chromium devs have no idea what the impact of their decisions are... and judging by the issue trackers they don't care.
