 I have an objection on renaming the existing option flags in ping6(8)
 for compatibility with ping(8).

 Is it sufficient to add INET6 support to ping(8) with consistent
 flags and keep CLI of ping6(8) backward compatible?  People have used
 ping6(8) for >15 years, so it is too late to rename the flags.  I do
 not think the renaming is useful if "ping -6 localhost" or "ping ::1"
 works.
