Since default column capability isn't part of the jdbc standard yet (but
since it is part of the SQL standard, I would expect it to be added
someday to the jdbc spec), adding support for it would require the user
to write non-portable jdbc code.  Since there is a portable way to
accomplish the same thing (i.e. not include the column in the insert), I
don't see a compelling reason to add this functionality.
