If it's not there, no one will ever miss it.  You might as well argue
that there should be a way of creating a foreign key reference by
ALTER'ing the referenced table instead of the referencing table.
Sure, if the SQL committee was into symmetry, they might have provided
such a thing.  But they didn't and no one misses it.
