This was kinda my philosophy until other devs started working on my project. I couldn't bring myself to tell them "no ES6" in PRs, but wasn't actually a review without knowing it. At some point I took the plunge. It is actually pretty nice for my uses, and I don't feel like I spent a crazy amount of time/energy learning. Mostly just a lot more productive.
