I think that would work, as long as modes only created their own
abbrev-table when the mode is clearly `unique enough' (compared to the
mode it's derived from) that most users would want to put abbrevs in the
derived-mode's table.  [with a :keyword command to define-derived-mode
to control whether a new abbrev table is made or not, this should be
simple for mode-authors]

E.g., probably `mail-mode' should have its own abbrev table, but
`paragraph-indent-text-mode' should not.

I suppose the question is, what should be the default behavior of
define-derived-mode -- to use the parents, or inherit?
