I would guess it's a readability concern. Consider a simple function
def f(x, y=0):
print x + y
for a in , "ab", "abc":
Can you tell what will be printed immediately? For me
f("a", "b", "c")
is much easier to predict.
That said, there are valid usecases for * and ** "magic", and of course
pylint cannot take the tradeoffs into account. Therefore don't take pylint's
warnings as gospel.
PS: the exception is intentional
