The flag is not needed. It is only possible to retrieve arp entries by
way of sysctl. The converse of this is you no longer need to grab all
the entries in the routing table and look at each one to determine
which are cloned routes (dynamic host routes) which contain ARP
entries.

Als die Nazis die Kommunisten holten,
habe ich geschwiegen;
ich war ja kein Kommunist.
Als sie die Sozialdemokraten einsperrten,
habe ich geschwiegen;
ich war ja kein Sozialdemokrat.
Als sie die Gewerkschafter holten,
habe ich nicht protestiert;
ich war ja kein Gewerkschafter.
Als sie die Juden holten,
habe ich geschwiegen;
ich war ja kein Jude.
Als sie mich holten,
gab es keinen mehr, der protestieren konnte.
