This is not true. A look in the data integrity section in:

     http://www.openssh.com/txt/draft-ietf-secsh-transport-14.txt

shows that the MAC is also optional. If one is using ssh on a VPN connection,
it is quite reasonable to get rid of the ovhds of both the encryption as well
as the MAC. An example again is when one is forwarding X connections using ssh
over a VPN connection.
