Not necessarily. You could build multiple targets and dynamically serve one over...

Isn't that what the parent said?

What tools do you use to make it happen?

Still working it through. The steps as I see it:

Figure out which browsers to support on which features: https://kangax.github.io/compat-table/es6/

Have an alternate .babelrc with a transpile blacklist that points to a separate dest

Build a regex to match those browsers in your CDN (I use Fastly). Vary on the value you create.

Point said browsers asking for the normal JS payload to the alternate dest.
