> So the easiest way to solve this is: Declare everything you need as keyword argument, but then only give *kwargs in your function signature to allow your __init__() to handle any set of arguments your children or siblings may throw at you. Then remove all of "your" arguments via kwargs.pop('argname') before calling super().__init__() in case your parent or uncle does not use this kwargs trick and would complain about unknown arguments. Only then pass on the cleaned kwargs to your MRO foster parent.

The easiest way is to not put your arguments into kwargs in the first place. If you put them as regular function arguments (probably give them a default value so they look like they're related to kwargs), then the python runtime separates them from the rest when it generates kwargs and you don't have to do the ".pop()" part at all.
