Most browsers warn you if you are about to close multiple tabs.... I guess chrome doesn't? Weird.
That would be an implementation problem for chrome - every other OSX application tends to properly warn you if you are about to close multiple context windows with cmd-q.
EDIT: Just researching a bit- this seems to be a conflict between the Chromium design goals and the OSX UI guidelines... the Chrome team absolutely refuses to add a warning dialog if you try to close multiple tabs, but it would be the expected behaviour on OSX.
I tend to fall on the side of OSX - part of what makes it great is UI consistency - and this is one case where Chromium is making things worse, not better.
I'm 99% certain that this is a Mac-only option for now. It might make it's way into the other OS builds, but I don't think it is currently set up for them.
I think that the best approach would be do have a warning as default, except from in "Incognito" mode - that way, people who feel a need to quickly close the browser can use Incognito mode or disable the warning and the rest of us avoid troublesome accidental closing of the browser.
