Others have already covered the major points, but I wanted to highlight one
thing you said specifically:

Right. Your *current* HMD is hanging around your desk somewhere. But your
*future* HMDs are probably going to look a lot more like HoloLens: Self
contained devices with no external monitor. We still want a browser in this
environment, and we still want WebVR. So now that mildly annoying ad
doesn't just light up your HMD while you're not wearing it. It takes over
your entire field of view without your consent and at any moment, and is
allowed to re-take-over your display repeatedly. Does this still sounds
like a Bizarro thing to be afraid of?

(Also consider this is a real problem for Mobile VR today. Even if it's not
in an Cardboard/GearVR/whatever WebVR would take over the display and show
you the stereo split screen view. World ending? No. Annoying? Absolutely!)
