Planned for
No widgetId in automatically generated EditorInterface entities
With this change we'll stop to provide default widgetId properties for controls of EditorInterface entities when generating them automatically for newly created or updated Content Types. The consuming application should determine the default widget ID on its own.
The Contentful Web App is the primary consumer of this API. It already doesn't rely on this behavior.
This change concerns you only if you maintain your own replacement of the Contentful Web app and reuse EditorInterface entity for management of its appearance.
