Closely monitor this situation, in case Babel forks core-js or something.

Babel maintainer here 👋
We are probably not going to fork core-js because we don't have enough resources to maintain it. We are investigating if it's possible to provide an integration for es-shims/es5-shim/es6-shim.

That’s unfortunate but understandable.

Sounds great, but what about ES2016 and above functionalities?

[nicolo-ribaudo]

es-shims also provides modern polyfills: https://github.com/es-shims

[ryanelian]

Nice.

I guess it's my cue to start cherry picking changes from those repository on my spare time then...

Actually, might revisit the idea of using FT Polyfill too: (Looks fairly maintained)

Will do this for TypeScript 4.0.0 release:

Develop polyfill library for TypeScript based on es-shims. Babel team has been diligent in documenting which polyfill library should be used for which ECMAScript feature:
