Comment (by youknowriad):

 I've been thinking a bit more here. It is possible that some plugins are
 declaring `wp-polyfill` as a dependency but are still compiling generators
 to use the generator runtime. It would be a small breaking change for
 these plugins.

 To be honest, I have no idea if there are such plugins and their numbers,
 but thought I'd mention.

 We could advise them to:

  - Update their build tools to not transpile generators.
  - Add `regenerator-runtime` dependency explicitly.

 I'd probably recommend handling that in the dev note for now (and keep an
 eye on feedback).
