Limiting JavaScript?

In the issue, Craig Hockenberry makes the case that enforcing a limit on the amount of JavaScript would provide a sort of “meet me in the middle” solution for users currently using content blockers. One thing that seems to be forgotten when we see browsers suggestion things like resource limits, or selective disabling of JavaScript, is that they aren’t going to roll something out to the broader web that is going to break a ton of sites. Currently the idea with Never-Slow Mode would be to selectively roll those restrictions out only for limited situations, according to Alex:

In other words, they would take a very gradual approach like the did with HTTPS Everywhere, focusing on specific situations to apply the restrictions and careful consideration into how to progressively enable a UI that keeps users informed.
