How to safely grant ALTER SYSTEM KILL SESSION “privilege” to non-DBA users

CREATE OR REPLACE PROCEDURE sys.sp_kill_dev_session(p_sid NUMBER, p_serial NUMBER)
AS
    v_user VARCHAR2(30);
BEGIN
    SELECT MAX(username)
    INTO v_user
    FROM v$session
    WHERE sid = p_sid
      AND serial# = p_serial;

    IF v_user IN ('SCOTT') THEN --the list can be extended
         EXECUTE IMMEDIATE 'ALTER SYSTEM KILL SESSION ''' || p_sid || ',' || p_serial || '''';
    ELSIF v_user IS NULL THEN
         RAISE_APPLICATION_ERROR(-20001,'Session has Expired or Invalid sid/serial Arguments Passed');
    ELSE
         RAISE_APPLICATION_ERROR(-20002,'Unauthorized Attempt to Kill a Non-Dev Session has been Blocked.');
    END IF;
END sp_kill_dev_session;
/

IF v_user IN ('HIRXPXT','PHU_XDMIHHION') THEN --the list can be extended

GRANT EXECUTE ON sp_kill_dev_session TO HIRXPXT;

exec sys.sp_kill_dev_session(sid,serial num);

exec sys.sp_kill_dev_session(154,42802);

SELECT SID, SERIAL#, STATUS, SERVER
FROM V$SESSION
WHERE USERNAME = upper('<username>');
