What's wrong with HTTP is that there's no real benefit to using it in a real-time environment. There's no point. We use reliable UDP abstractions today to accomplish this. Everyone does. There are countless articles on why TCP didn't work for video games, or of the ones that use it today, it's in an extremely limited sense.

I can't think of a single reason why you would go out of your way to serve HTTP over UDP for the purpose of communicating to a user agent for s/video games/virtual reality/, because no one has done that in over 20 years and if it was a good idea, it would have been done by now. But no one does it. Because there's no point.
