Investigate: Remove webpack `resolve.alias`?

We have all our package.json:dependencies hard-coded as resolve.alias for our core webpack configuration to ensure:

1. Needed deps are in the require resolution path (since CLI may be outside of this path); and,
2. To make sure we only have one installed library for those offenders that have singleton state (react, react-dom, etc.)

Task

• See if we can avoid doing this hard coding?
• Check unintended consequences for continuing...

Start with package.json dependencies and the core webpack configuration. Investigate whether the hard-coded resolve.alias entries are still needed for CLI require resolution and singleton libraries such as react and react-dom. Done means documenting the consequences and determining whether the aliases can be removed safely.
