Problem

0d4c039 + 53784ec were landed as improvements to the experience when scaffolding a new plugin w/ Webpack, but due to the switch to migrations for update instead of re-creating all the files, existing plugins cannot benefit from these changes.

Solution

Create an addition script that allows plugin devs to optionally apply these recent changes.
