That may be true, but that was not in the code as such. The p2p-dev 
wpa_s gets the main configuration applied without any filtering when no 
-m config is specified. My just posted patches try to fix that skipping 
network parsing, but still not sure if that is the best way. Could also 
disable/remove the networks from the p2p-dev config after parsing completes.
