Why? If there's no ListenAddress ssh listens on all addresses:

---
     ListenAddress
             Specifies what local address sshd should listen on.  The default
             is to listen to all local addresses.  Multiple options of this
             type are permitted.  Additionally, the Ports options must precede
             this option.

(from sshd(8) )

and the ListenAddress 0.0.0.0 directive breaks IPv6 support (in january/2000
the openbsd branch changed that so it works. Why reverting the change and
breaking again IPv6 support?)

Thanks,
