No standard says we cannot behave the way we do.
You can control the behavior by setting the preferred source
on your routes using the 'ip' command and then setting the
/proc/sys/net/ipv4/conf/*/arp_filter sysctl values to '1'
for the interfaces where you'd like the preferred source to
determine what arp responses will occur.
