I think you misunderstand the way that python arguments work. If you have a function so:
def func(size=None):
Then func(0) and func(size=0) are equivalent, and func(0, size=0) is a TypeError because you've provided two arguments instead of just one. The C code *can* emulate this, but often doesn't (it just accepts positional arguments instead). An issue was raised about changing most C functions to support the keyword syntax, but I believe it was decided that while in general doing so is good we'd only do it on a case by case basis as they came up. See issue 8706 for more details.
