But just to be even clear, the new feature gate for ES6 is officially closed.
It's a really high bar to get over that closed gate. Unless the exclusion of a feature was a mistake, fixes a bug, or is somehow essentially to supporting something that is already in ES6 I don't think we should be talking about adding it to ES6.
I don't think String.prototype.at fits any of those criteria. We've talked about it several times, including in the context of Norbert's original ES6 full unicode support proposal, and never achieved consensus on including it. Personally, I think it should be there but it's time to start talking about it for ES7 not ES6.
