We've discussed having the shell interpret F11 for fullscreen, the problem is that means apps would not receive that key any more. While a common standard, it's conceivable that some apps have F11 as a functional key, so we'd have to take that away from them.
We've decided it's the app's responsibility to handle F11 for fullscreen. There will, however, be another shortcut - Ctrl+Super+Up, that's used today to maximize an app, and we'll allow for that to make a maximized app fullscreen.
