I will be pretty happy if I see non-ES6 code if it is properly structured and documented well. Nevertheless if I see people has just replaced `class` with `jQuery.extend` or with some other helper tool it would be a downside. Also we are talking about lodash vs native implementation. That's one of the reasons I stopped working with coffeescript.
