How many ES5 environments are still in use today?

We still use ES5 for development, since our server-side platform (GPSEE)
doesn't run on later SpiderMonkey (embedding API made massive changes a
couple of years ago and we haven't had resources to update.....massive

I am working closely with another company right now that uses NodeJS.  It's
nominally ES6, but ES6 modules are not available in typical deployments,
which is a pretty major missing feature.
