Why use positional only arguments in pythin 3.8 : A new "positional only arguments" syntax has been introduced in 3.8.

My question is, why ever use this syntax?

Why is it better for the code's user?

It seems to me that this makes it harder for users to specify what their arguments actually mean, if they so desire.

Why make it harder on the user?

I am clearly missing something.
