Might as well be consistent with these different operations

Since the default argument is None, wouldn't that cause issues?

According to https://pandas.pydata.org/pandas-docs/stable/reference/api/pandas.Series.cumprod.html#pandas.Series.cumprod the default argument is 0

I see what you mean, I was looking at the 2.3.0 code which still has None as default but on main it is now 0 (I would not see anyone use None by default and otherwise it will make it a good time to fix it).

This doesn't seem right, and I think you'll need some specific overloads here for RangeIndex (and Sequence[int] for that matter). If RangeIndex has a set operation with either a Sequence[int], Series[int], Index[int] or RangeIndex, the result is Union[RangeIndex, Index[int]]. With any other type, it is just Index

Indeed that was the wrong copy paste, this is fixed.
