I have used proxy_arp successfully without having to add pub entries
to the arp table. I create the routing table with appropriate host/net
routes, then do
echo 1 >/proc/sys/net/ipv4/ip_forward
echo 1 >/proc/sys/net/ipv4/conf/eth0/proxy_arp
echo 1 >/proc/sys/net/ipv4/conf/eth1/proxy_arp
The kernel will then automatically generate arp replies when it
receives an arp requests on the 'wrong' interface (ie. where the
routing table says the target is on a different interface from the
interface that received the arp request).

No.
