feature

What is the current behavior?
targets are pretty restrictive and a web bundle can't be used in node or webworker.
If the current behavior is a bug, please provide the steps to reproduce.

What is the expected behavior?
The universal target includes runtime code that runs in web, webworker and node.js. The code can be a bit bigger to support all of them.

If this is a feature request, what is motivation or use case for changing the behavior?

• Create UMD bundles that work in all enviroments
• Create bundles with chunks shared between web and webworker.
