TC39 has a famous "don't break the internet" mantra. Even the leeway that Python has with deprecations/features JavaScript doesn't. It's versionless, code automatically gets updated to whatever the browser is using.

JavaScript evolves quickly but so does Python!

(Note that your approach is exactly what they said in the 2 to 3 transiton btw with a special tool that didn't work too well)

That’s not what that library was in my opinion, it was a compatibility layer not a rewriting tool which is what I referenced. Having a layer in between simply prolongs the issue and creates many types of problems based on adoption or not. On the other hand, when rewriting you can apply that either as an author or as an end user depending on the quality which meaningfully allows for different results.
