I'm guessing browsers would have to enforce some artificial restriction on the eval function, possibly prompting the user with "This webpage is attempting to run a large amount of [insert user-friendly layperson terminology here]. This may be related to advertiser abuse. Do you want to allow this?" But it's not clear how they plan to solve it for iframes either which could essentially grant unlimited JS as well. They have good intentions with the discussion and it's an interesting idea but I don't see it becoming reality until they can solve these problems which seem actually rather hard.
