Move playhouse module as a submodule on peewee?
This is simply how peewee is organized. Peewee is a standalone python module and all extras/extensions are included in a separate namespace. I see your point. My suggestion was to move naming in the direction of making `playhouse` module name more related to peewee. A middle ground may be `peweeplayhouse`? It's been this way since ... 2010? I'm not too interested in changing it.
Finding in source code something like `import playhouse.shortcuts` is not very specific or self-explaining IMO.

A big leap would be moving at least some functions like `model_to_dict` / `dict_to_model` to stock peewee, but even making them `peewee.playhouse.model_to_dict` would be more discoverable.

Thanks for a great package!
