About video in particular, why would we not want video to be keyboard
accessible in full-screen? I very often pause/unpause and seek using the
keyboard when using standalone video players, and I'd like to do the same
in the browser as well.

Do you think we should have different permission levels in full-screen
which come with different levels of user prompting?
I don't think a persistent overlay is acceptable for either games or video
and keyboard input is needed for both. (No, I don't think it's acceptable
to require a mouse for video.)
