Francesco,
Yes and no. In the most basic sense, the **kwargs are generally considered
as optional. However, in some very advance python code, we use the
argument unpacking features of (*args, **kwargs) to create a more agnostic
API (duck-typing for call signatures, if you will). Unfortunately, I don't
think we can update the call signature until we can drop python 2.x support.
The doc string you see when you look up FloatingSubplot is actually from
the class definition a few superclasses up. If this makes no sense, you
aren't alone... The way FloatingSubplot is made is extremely convoluted and
I am still trying to wrap my head around it. A docstring should probably
be added for the __init__ function of FloatingAxesBase so that its
constructor could be better explained.
