The legacy extended json encoding of DatetimeMS is incorrect:
>>> dumps({'d': DatetimeMS(1)}, json_options=LEGACY_JSON_OPTIONS)
'{"d": {"$date": "1"}}'
It should be encoded as a number, not a string:
>>> dumps({'d': DatetimeMS(1).as_datetime()}, json_options=LEGACY_JSON_OPTIONS)
'{"d": {"$date": 1}}'
Attempting to decode the incorrect string version results in a decoding error:

This was introduced when we added DatetimeMS in PYTHON-1824.
