While I agree here, you also have to remember that additions to the JavaScript standard also increase the amount of time / effort for new browsers to enter the space.
The JavaScript standard (the web APIs, mainly) are already very complex, with Web Workers, Push Notifications, Media Streams, etc. that additions to it should be made cautiously -- once an API is implemented, it's there forever, so the bar for quality is much greater than that of some NPM library.
Yes it should be done carefully. There are also plenty of examples of how this can be done well, done by experienced engineers. For example, the Dart starndard library (https://dart.dev/libraries - core [1], collection [2] and async [3] in particular) is a very good model that would fit JS fairly well too (with some tweaks and removals)

It's still a nonzero amount of complexity. I see a lot of "v8 is really hard to compete with" comments on here so this feels very pertinent to mention. You can't have it both ways.

This one, at least, looks somewhat inspired by JavaScript.
That sounds great, but I'm doubtful of the simplicity behind this approach.
If my understanding is correct, v8 has transitioned to C++[0] and Torque[1] code to implement the standard library, as opposed to running hard-coded JavaScript on setting up a new context.
I suspect this decision was made as a performance optimization, as there would obviously be a non-zero cost to parsing arbitrary JavaScript. Therefore, I doubt a JavaScript-based standard library would be an acceptable solution here.

(Or are they still trying to make Servo viable?)
There's plenty of competition, even if the current projects are in a beta (or even alpha) state. Consider the LadyBird browser developed by SerenityOS, or Servo.
