Our most likely short-term goal would be the latter (enabling capability detection) but I wouldn't take full keyboard access off the table forever. We would want the freedom to apply different security policy to that case when/if we do it though.

Many games could work with only non-alphanumeric keys or in some cases only the mouse. As could slideshows. You only need space/enter/arrows for a full screen slide presentation.

What are the cases where webpage-driven (as opposed to browser-chrome-driven) fullscreen is really compelling, but they need full keyboard access including alphanumeric keys? (Not saying there aren't any, I am just not sure what they would be - fullscreen Nethack?)

Likewise.
