I can't think of single reason why you'd need proxy-arp, ever.
However, for residential connections local-proxy-arp is commonly needed feature
and for some cruel and unusual reason local-proxy-arp does not work without
having proxy-arp also on (at least this was the case in 12.2SB, hopefully
fixed since, didn't bother opening DDTS, but just as writing this, I
checked for DDTS and fond CSCds43725, no fixed IOS' so far)
