@babel/preset-env, useBuiltIns: 'usage' and regeneratorRuntime

[thernstig]

https://babeljs.io/docs/en/babel-preset-env#usebuiltins-usage says it adds polyfills. But I assume it also adds regeneratorRuntime (which is not a polyfill)? Should that be explicit somewhere in the usage part? Since I assume usage doesn't do anything else than to add core-js Polyfills and the funciton regeneratorRuntime?

Hey @thernstig! We really appreciate you taking the time to report an issue. The collaborators
on this project attempt to help as many people as possible, but we're a limited number of volunteers,
so it's possible this won't be addressed swiftly.

If you need any help, or just have general Babel or JavaScript questions, we have a vibrant Slack
community that typically always has someone willing to help. You can sign-up here
for an invite.

I'm confused about this same thing. Some clarification would be helpful.

+1. The usage description should mention regeneratorRuntime, not just core-js.
