Yes that's exactly the point Gallantmon was trying to make. The popup
API was created, people abused it, hence pop-up blockers. However, we
have already seen that since the creation of flash's full-screen API,
people haven't abused it. So there's no real argument for not
including it in HTML5 video.

You might say "But people might abuse it in the future and then we'd
be stuck with it!!", but this isn't correct. Whereas we are somewhat
stuck with popups, with HTML5 video you could always disable the API
via a preference, and still access full-screen manually via the
context menu.

Yeah I don't think it is critical. I assume it is wanted so web sites
(e.g. youtube) can display custom full-screen buttons.
