pg_get_viewdef in its current form is needed for the
information_schema "views" view, which has separate columns for the
view's query and its CHECK OPTIONs.
Arguably another function could be added. However, given the need for
psql to support older server versions, a new function wouldn't
actually help much, since psql would still need to be able to do it
the hard way in the absence of that new function on the server.
