Comment (by Simon Charette):

 There's enough significant differences between `json` and `jsonb` types
 which makes me believe this is not a good idea.

 For example, [https://www.postgresql.org/docs/9.4/datatype-json.html
 containment operators it not supported] on `json` columns while they are
 on `jsonb` ones which breaks the `__contains`
 [https://docs.djangoproject.com/en/2.2/ref/contrib/postgres/fields/#std
 :fieldlookup-hstorefield.contains operator].
