Offer (browser) ESM distributions for proposed replacements to @babel/polyfill

[brettz9]

Feature Request

Is your feature request related to a problem? Please describe.

@babel/polyfill has been deprecated in favor of core-js and regenerator-runtime, but neither of these offer an ESM distribution built for the browser, so I'm forced to do my own building now even for applications such as demos where I wanted to avoid polluting my repo with such.

Describe the solution you'd like

Working with core-js and regenerator-runtime so they may offer such builds to continue meeting the needs of @babel/polyfill users.

Describe alternatives you've considered

Building: This, besides being a hassle to have to do for every consuming project, is an obstacle for rapid debugging, and deters one from use of new ES features and quick development.

Teachability, Documentation, Adoption, Migration Strategy

This will ease the migration to core-js and regenerator-runtime for projects which don't need or wish to do their own building. Just as prominent projects provide pre-built binaries, I think these highly important polyfills deserve their own pre-built modules.

Hey @brettz9! 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.

Thank you for the suggestion! This feature request should be discussed in the core-js and regenerator repositories, since in Babel we can't do much about them.
