    It means that systems (like Linux) that make IP addresses owned by the
    host instead of specific interfaces cannot correctly interoperate with
    such remote systems.

    It is also the case that a host cannot possibly be aware of all
    subnets present on a given LAN, therefore is should be liberal in it's
    replies to ARP requests.

    Finally, it violates the most basic rule of IP networking:

    "Be liberal in what you accept, and conservative in what you send"
    -Jon Postel

    In general, when a host posses the information necessary to allow
    other hosts to communicate, it should provide that information
    whenever possible.
