[j-nsp] static arp with unnumbered-address

Hello

How do you program in a static arp entry on an interface that is using
family inet unnumbered-address ?

Eg.:

interface ps1 {
    unit 2766 {
        proxy-arp restricted;
        vlan-tags outer 402 inner 1016;
        family inet {
            unnumbered-address lo0.1;
        }
    }
}
routing instance internet routing-options {
    interface et-0/0/0.2766;
    static {
        route 192.0.2.11/24 {
            qualified-next-hop et-0/0/0.2766;
        }
          route  198.51.100.22/24 {
            qualified-next-hop et-0/0/0.2766;
        }

It is not possible to have the juniper router do correct arp in this case.
You can have the 192.0.2.0/24 range working or you can have the
198.51.100.0/24 working using preferred source address but not both. So I
figured I could get away with simply hard coding the arp entry. However
static arp is in the family inet address subtree so can not be specified
here. Seriously ?
