I think zepto is using that to modify runtime NodeList results after querySelectorAll but in any case it was not me saying that __proto__ is used already. I use it only to shim getPrototypeOf to be honest and I don't think is a good idea to use it at all.
My point is that Object.setPrototypeOf does not need a property loads of shenanigans as __proto__ is so that no Object.prototype.__proto__ would ever exist anywhere. I don't even know why that existed in first place,to be honest ... so do not use it, pass through Object.setPrototypeOf, same as you would suggest pass through Object.defineProperty instead of using Object.prototype.__defineGetter__ __defineSetters__, both "de facto standards" some time ago. So, reverting the question, what is **your** point saying that __proto__ is better than Object.setPrototypeOf ?
