Would it be worthwhile to show an example of a subclass that overrides or extends __new__?
Elsewhere in Python, the usual technique for changing method defaults is for a subclass to override or extend the method in question.
class A:
def somemeth(self, value: bool = True):
print(value)
class B(A):
def somemeth(self, value: bool = False):
super().somemeth(value)
