I found, theoretically by reading 802.11 specification,
broadcast/multicast reliability problem and reported to
IPv6 WG about 20 years ago. So, I'm pleased to know
that some people recognize it as a real problem and
worked on it. Thank you.

Aren't IP addresses are assigned from APs? Then, the
APs can construct ARP table without actually running
ARP or inverse ARP, I'm afraid.

An ARP table entry can be created when an IP address is assigned
during registration process and destroyed if the registration is
invalidated.

Or, do I misunderstand anything?
