Here's a link to the original discussion about this in 2011:

When I added IPv6 support to this code, I sent Yoshifuji-san patches
to iputils to use it. Unfortunately iputils hasn't seen a release
since then. I guess that's why a new binary is still required.

FWIW, Android uses this code because it does not allow setuid binaries
and so it's the only way to run ping on Android. Other distributions
(like openwall) probably have similar requirements. Of course that
doesn't mean it can't be optional. It would be nice if it wasn't
ripped out though :-)
