I'm not sure what "this solution" here is referring to. Use of three
different MAC addresses? Or the new dedicated non-netdev P2P_DEVICE?
Neither of those is needed for P2P cross connection.

Sure, and that works just fine with wlan0 being used for managing P2P
operations and for the infrastructure AP connection while another netdev
is used for the P2P group (i.e., just two MAC addresses and no need for
P2P_DEVICE concept).
