Yes, but from man chattr:

BUGS AND LIMITATIONS
       The ‘c’, ’s’,  and ‘u’ attributes are not honored by the ext2 and ext3
       filesystems  as  implemented  in  the  current mainline Linux kernels.
       These attributes may be implemented in future versions ext2 and  ext3.


perhaps they haven't bothered because just overwriting with zeros is not really what some consider secure anyway?
