RFC 1127 ("Perspective on host requirements"), section 4, item 2:

    Even without proxy ARP, the management dynamics of the IP route
    cache interact in subtle ways with transport-layer dynamics;
    introducing routing via proxy ARP brings a third protocol layer
    into the problem, complicating the inter-layer dynamics still further.
