Looking at the code, this seems to be intentional, because the privilege
check is not made for revokes only for grants:

        if (stmt->is_grant
            && !pg_class_ownercheck(relOid, GetUserId())
            && pg_class_aclcheck(relOid, GetUserId(),
                                 ACL_GRANT_OPTION_FOR(privileges)) != ACLCHECK_OK)
            aclcheck_error(ACLCHECK_NO_PRIV, ACL_KIND_CLASS, relvar->relname);

Peter, do you remember why you did it that way?
