It would make them behave the same way as almost everything else, thus 
following the concept of feature parity between IPv4 and IPv6.

No need to modify scripts.  Provide a hardlink to ping6 and add code 
that checks argv[0] and runs in compatibility mode if called as ping6. 
We can then use this opportunity to homogenize the IPv4 and IPv6 ping 
parameter assignments without breaking backward compatibility.
