I think this would fail if a user passes to_datetime(np.array([...], dtype='datetime64[ns]'), utc=True)?
I was thinking more:
if box:
if not isinstance(arg, (DatetimeArray, ...)):
....
elif tz:
...

>>> arr = np.arange(2).astype('datetime64[ns]')
>>> to_datetime(arr, utc=True)
DatetimeIndex(['1970-01-01 00:00:00+00:00', '1970-01-01 00:00:00.000000001+00:00'], dtype='datetime64[ns, UTC]', freq=None)
or are you suggesting that this is wrong because box=True was not passed?

Oh! It does work. box=True is the default so this looks correct.

to_datetime(naive_dti, utc=True)returns naive incorrect, same for naiveDatetimeArray
