802.11b is at layer 2. Ping (layer 3), P2P and network shares (layer 7)
are clearly above that, so they will not work with ap_bridge_packets=0

Set ap_bridge_packets=0.
Assign a separate subnet for each of your clients.
Assign the respective gateway IP's to your hostap interface.
Disable redirects on your hostap interface.
Use iptables to filter the traffic.

I believe that was the original intent and nothing more.
There's no point in duplicating existing funcionality.

See above. I would not call it a "workaround", though.
