that you'd likely never want to pass just True, but that
numeric_owner=True would be a better usage.

At least asyncio uses keyword-only intensively.

Hi Andrew,
Is someone asking where to find resources to learn Python. We have
redirected him to the python lists both in english and spanish.
We should have replied in English if it would have been something related

I personally find that keyword only arguments make for nicer APIS. It also
makes subclassing easier because you are free to add new positional
arguments later. Especially for boolean arguments, I think keyword only is
a great API choice.

If you’re introducing a new parameter that is a boolean, making it kw-only is
generally accepted. Some people (myself included) would encourage you to do so.
Besides asyncio, there are already new arguments that are kw-only in many
modules, including configparser, unittest, xml.etree, xmlrpc,
