The salient difference is:

With the former set, they all embody concepts of either “empty” or “zero
magnitude”. They strongly connote “not there” within their domain of
values, hence map well to Boolean false.

With ‘datetime.time’ there is no equivalent: midnight is not special in
the way “empty” or “zero magnitude” are. Midnight is an arbitrary point
on a continuum, and is not a “not there” value. It should not be Boolean
false any more than any other time.
