Review Comment:
   I put the serializable namedtuple behind a `return_serializable` flag, which 
is False by default. With a warning for a future release of the provider, where 
it would turn to True by default. And eventually later the flag can disappear 
too to only return the namedtuple.
   
   What do you think ?
