Not entirely sure how you expect this to work?

We need to be able to statically extract which modules to create otherwise we can never create bundles reliably on build. Maybe a regex of bundles to create and we inject an index mapping to the hashes in the js bundles?

This seems more of an RFC thing than an actual bug
