I'm afraid you misunderstand my point.

ARP is perfectly good for CSMA/CD but not so good
for CSMA/CA where broadcast/multicast is unreliable.

So, with wifi, we should rely on repeated beacon from
base stations for AR of the base stations and rely on
unicast from clients to register them to base stations,
which should act as proxy for communications between
clients, which is a totally different protocol from ARP.

Without such recognition today, wifi users should be
suffering from some inefficiencies when link is congested,
which is often the case.

Other link technology should also require AR mechanism
of its own.

As such, performing AR with IP is not so meaningful.
Worse, even DHCP, which assumes reliable broadcast,
does not work so efficiently over congested wifi.
