I think the reason why we can't update a materialized view directly is because
it is basically a "view" and it should not contains any data irrelevant to its
definition and underlying tables. If we would have a feature to update a
materialized view direcly,  maybe, it should behave as updatable-view as well
as normal (virtual) views, although I am not sure....
