Why would anyone made such a change every year? Many people write articles about better ways to do X in many languages but that doesn't mean you change everything to follow that today. Maybe it informs your decisions tomorrow, maybe it doesn't. Ultimately you don't need to do anything here.

Personally I don't use promises and won't use this either but that's only because I am working on a code base that needs to work in more places (so no ES6 for me and no I don't need the extra complexity in my build and debugging steps to do a transpile).

I'd love to know which runtimes do you have to support which don't support ES6 if you don't mind? I imagine you're dealing with old browsers.

At my previous job it was older browsers but my primary avoidance of ES6 is related to my open source project (msngr.js) where I want to ensure I support not only older browsers but also node.js 0.10. I could use ES6 and transpile with babel but I try not to do that when possible to keep the build process as simple as possible.

If there was a specific ES6 feature that I think would hugely benefit my productivity or if I was working on a project that could utilize ES6 in other ways I would certainly use it more.
