The recovery and kiosk cases make sense to me, but seem pretty special-purpose.

The proposal here that doesn't make sense to me is the idea that I'm going to hand my computer to a friend (who I presumably trust with my Mac) and not trust them to sign out of my gmail when they want to check their gmail. Also, the use case of "Can I borrow your computer?" is almost always quick, and, in my experience, rebooting a Mac is not quick enough. I'd much rather give them my laptop with an incognito window open than resign myself to rebooting my laptop after they're done (even if application state saving works perfectly, rebooting is still a 30 second affair).

If they can make it quick, then it seems like a great idea, but forcing a reboot to get into this mode seems to relegate it to special cases.
