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.

I expect that's because keyword-only parameters are quite recent (3.x only) and most of the stdlib is quite old. Keyword-only feels right for this to me too. -- Steve
