Fair point. PySide does those kind of things (turning certain objects
into context managers, allowing optional snake_case access of
everything, etc.). But I'm not exactly convinced it's a good idea. Even
more so since obviously duplicating the entire Qt documentation is a
pain point, thus it's a good idea to stay close to upstream, so that the
upstream docs can be used.
