Comment (by spectacula):

 The expected and documented output for that part of the REST API is an
 array and Guttenberg fails because it assumes an array but is given an
 object.

 http://v2.wp-api.org/reference/taxonomies/#schema-types

 So passing the post_types array through '''array_values()''' before it
 gets to '''json_encode()''' would have the desired effect. Array keys
 aren't needed within '''register_taxonomy()''' so anybody passing the
 output of '''get_post_types()'''  will also see this problem.
