I agree, while this is a cool idea it doesn't seem to be useful beyond being a proof of concept of an optimization technique. For example, my browser rendered the faster.js version 50ms slower at this point: https://i.imgur.com/G5b10Ns.jpg https://i.imgur.com/G5b10Ns.jpg. It does appear to perform better in the long run (https://i.imgur.com/u3ApYYl.jpg https://i.imgur.com/u3ApYYl.jpg) but it's an improvement of less than 1%, and when your renders are taking 30+ms there are probably other things you should be looking at :P Also, unless I'm misunderstanding the README, using the plugin introduces the huge caveat of breaking code that uses "restricted names" (certain names of Array functions) - the example given is a class that defines a map() function, which apparently would cause some kind of failure. In larger codebases where you don't control all code used in production this seems like a big problem.
