Definitely fair, as time progresses I think cleaner patterns will emerge. By time many of the major libraries were around, there was a semi-standard Python programming style that was fairly easy to adhere to. Since this is somewhat of a paradigm shift for the stdlib it will take a little time too.

Personally I have been looking at some of the patterns taken by the team on aiohttp - I think they've done a good job and, iirc, one of their members is a core contributor to Python.
