I agree with you for the PBC case.

For the scenario where you display the PIN on one side and enter it on 
the other side, I tested provision discovery request:

 From WPA_supplicant (let's say left side), after a successful find 
phase, I do "p2p_prov_disc <MAC addr> display". On the right side 
wpa_supplicant, I get the message DISPLAY_PIN as expected and can see 
the computed pin. On the left side, I do p2p_connect <MAC addr> PIN_CODE.

 From my understanding, this sequence should lead to a a successful GO 
negotiation since the right side has the provision information.
But I see that the right side still send 0x1 error in the GO negociation 
response. Is my understanding good according to you ?
