Description

Thanks for the talk today at WebPerf!

I have a concern about whether this would really work in the way it's expected. One thing I don't understand what makes a document want to opt-in for this, because opt-in actually gives more restriction to it, I don't expect anyone would prefer that?

This also feels like potentially adding "disadvantages" to browsers who implement this because this could potentially slows something down (due to a violation).
