That would be an odd back-step since Python 3 generalized the built-in:
>>> class Test:
... def __round__(self, ndigits=None):
... return 1
...
>>> round(Test())
1
Also, float, Decimal, and Fraction in Python 3 return an int when the
ndigits argument is omitted. For example, float rounds using the math
lib's round function, then rounds that to even, and returns
PyLong_FromDouble. Is the discussion just about removing the ndigits
aspect but keeping the round-to-int aspect?
