Comment (by herregroen):

 We're encountering this in Yoast SEO as well when testing with WordPress
 5.8.

 Reading the above I get the impresssion that the main difference is the
 lack of `regenerator-runtime` in `core-js/stable`.

 If that's the case it could be worth looking into the option of keeping
 `wp-polyfill` around only as an alias rather than reverting the change
 entirely and having that alias depend on both the new polyfill package as
 well as a separate `regenerator-runtime` dependency.

 I'm not sure if that covers the full scope of the changes but it could be
 an approach worth looking into.

 That said, I do agree that it's very likely that a lot of plugins and
 themes will depend on `regenerator-runtime` and thus removing it is not an
 option. So either a revert or using `wp-polyfill` as an alias that
 enqueues both should be done.
