I think this will make it easier to get #49365 working.
Could you see if this addresses https://github.com/pandas-dev/pandas/issues/32526, https://github.com/pandas-dev/pandas/issues/32174? Definitely doesn't fix #32174.  looks like it makes #32526 better but that is a bit fuzzy on when we'd call that "solved" Just a heads up, I think you linked `pull/32174` instead of https://github.com/pandas-dev/pandas/issues/32174 Thanks @jbrockmendel (makes `Timestamp.__new__` more sane)
