 The Gutenberg repo has been using a `GUTENBERG_PHASE` environment variable
 for a while to feature flag particular features (mostly experimental

 When the packages from Gutenberg are compiled by webpack in core, the idea
 is that this feature flagged code is removed from the build via webpack's
 dead code elimination feature.

 The variable was set to integers representing the phases of Gutenberg
 (core set to `1` and gutenberg set to `2`), so that when the project moves
 to a new phase the value is incremented. That didn't really turn out to be
 a useful approach though.

 Recently in the Gutenberg project this variable was renamed to
 `IS_GUTENBERG_PLUGIN` and changed to a boolean

 It should now be possible to remove this configuration from WordPress core
 and rely on the falseyness of it being `undefined`.

 Here are the details of what needs to be removed:
