RxJS's pipeable operators should allow the build process to eliminate dead code, meaning that only the utilised operators are included in the final bundle.
Actual Behaviour:
Importing NgReduxModule results in all RxJS operators being included in the final bundle.

Additional Notes:
I think this is happening because the tsconfig.build.json file is using the module setting of commonjs rather than es2015.
