In general, it's not the TC39 who should be dictating how code is
written - in particular, even they have their stylistic disagreements
(like with ASI and `let` vs `const`), and active TC39 representative
maintain both JSHint (opinionated) and ESLint (unopinionated).
Additionally, JSLint (the predecessor to JSHint) was created by a
formerly active TC39 representative. If you want to see more of these
broad stylistic disagreements, check out [their meeting notes]. A
few things that come to mind are decorators, cancellation, recent
class additions, and [BigInt].
Instead, if you have your own strong opinions on everything, try
introducing [ESLint] to your projects. They have numerous presets
and rules built-in, and you can create your own custom presets, rules,
and plugins. If you want to ban `null`, write a custom rule for it. If
you want to ban anything not ES5, write a rule that catches every
expression that isn't ES5. If you want to define local rules, use
[eslint-plugin-local]. In my case, I decided I didn't want to use
default exports, so I wrote a local rule banning all default exports.
Not that I have a problem with those who use it - I don't. I just feel
it's easier for me to wrap my head around named exports without
introducing the cognitive overhead of default exports.
