"ES5 functions" - by which you mean, *normal* functions - are not "outmoded", they remain necessary for any use case where `this` needs to be determined at invocation time.
Nothing should ever produce an arrow function without `=>`; and exports assuming `const` is an interesting idea, but explicit > implicit, and "typing less" is simply not a goal worth optimizing for by itself.
