I have not heard of such implementation yet, but I may add the wpa_msg()
calls soon(ish) to send the notification messages that would be needed
for this functionality since I need them for other purposes anyway.

hostapd ctrl_iface is somewhat behind the one in wpa_supplicant, but I
think it can handle wpa_msg() events now. In other words, it should be
enough to add wpa_msg() calls with a prefix defined in wpa_ctrl.h into
the proper places for association/disassociation and then add the
'wpa_cli -a' like functionality into hostapd_cli.

Assuming it is licensed in compatible way, yes.
