I think you might be misreading the parent statement as "I will never write JS > ES5". I too find that the easiest to implement features are (not terribly surprisingly!) the least interesting; they are not worth the terrible friction that I'd see in my current organization. I have a hard enough time trying to get folks to write good test coverage and understand the gotchas of writing async code everywhere. So for me, there's way bigger fish to fry than (exaggerating a bit here) saving a few characters with arrow functions. But that's still not to say I won't ever use it.
