Comment (by seebeen):

 Injecting scripts with appendChild can (and will) break minification and
 concatenation in caching plugins.

 I think a better approach would be to either enforce a minimum browser
 version which will also have a side-effect of not caring about backwards
 compatibility or implement asset compiling and transpiling via webpack and
 browserlist file.

 Second option can also generate all the needed polyfills via core-js
 module.
