That's a good point, and one of the reasons I've been reluctant to use much ES6 until it's solidly baked into > 95% of the browsers / devices / etc. (delivery platforms? whichever descriptor) that I would need to support. A transpiler just adds another layer of complexity that it's best to avoid as much as possible, in my opinion. It's not a perfect example, but if you've ever worked with CoffeeScript and run across a bug or unexpected side effect in the final rendered code . . . that should curb some of the transpiler enthusiasm. Some of the ES6 features look handy enough, but I'd prefer waiting to see which ones shake out as actually useful over time, versus which are just momentary novelties.
