By all means.  That is not what the ITU has been doing.  Redefining UTC to cease leap seconds is the opposite of a solution.

Aerospace also points things downward for innumerable purposes.  Navigation deals with tangential motions on the surface, in the air and at sea.  Pointing is not the only verb; see http://futureofutc.org for presentations and preprints touching on other areas.

Astronomers among others are power users of both solar time and atomic time.  The common ground is to recognize that these are indeed two different things.  Correct implementations cannot flow from faulty conceptual models.
