Could we first merge my PR #9808 first, which unifies the normal and noConflict mode. I can rebase this one if needed.

[zloirock]

@xtuc initially, I wanted to do it in this PR. However, since @babel/polyfill is deprecated and too many people use a link to packages/babel-polyfill/src/index.js for show that @babel/polyfill is just core-js and regenerator-runtime import, I decided not to do it.

[nicolo-ribaudo]

Well, people can just link packages/babel-polyfill/src/noConflict.js. If you want, we can add a comment in index.js pointing to that file.

[zloirock]

@nicolo-ribaudo I mean existent links.

I don't care.

[xtuc]

Sorry I think i'm missing something. Users that require packages/babel-polyfill/src/index.js will require the noConflict.js + actual conflict code under the hood. I don't think it's breaking exisiting links.

[zloirock]

@xtuc it's about links in the documentation / articles / comments.
