Fixing this for DataFrame is much harder, so punting for now.

looks fine. this is just a refactor right? doesn't change user facing?

No, this fixes corner cases failing to raise:

dtype = np.dtype("m8[ns]")
val = np.datetime64(1234, "ns")

>>> pd.Series([val], dtype=dtype)

>>> pd.Series({0: val}, dtype=dtype)

and vice-versa for flipping tdt64/dt64

@jreback

kk i guess then a whatsnew note
