Problem/Motivation
* - translations: (optional) Boolean, indicates if the entity is translatable,
* defaults to FALSE.
This doesn't seem right.
AFAIK, you set this to FALSE for the migration that handles the default language version. Then in a 2nd migration which does the translations, you set this to TRUE.
