Does babel-polyfills have any strategy to deal with repeated injection of different version of core-js library?

Quoted from there:

Your dependencies could have their own core-js dependencies and they can be incompatible with the core-js version that you use at the root of your project, so injecting core-js imports to your dependencies directly could cause breakage.

and more:

One more popular and similar issue is a duplication of polyfills from global and pure core-js versions. The pure version of core-js / babel-runtime is intended for usage in libraries' code, so it's a normal situation if you use a global version of core-js and your dependencies also load some copies of core-js without global namespace pollution. They use different internals and it's problematic to share similar code between them.
