Yes, it does. With ProcessCredentials set to False, a DBus client will
receive credentials and that's all. Basing this credentials the client
can set network parameters, etc. With ProcessCredentials set to True,
wpa_supplicant will additionally process and apply received credentials
to current network or add new network if no current is selected. This
settings can be stored then in config file if any used. In DBus-only
(just -u cmd option) configuration ProcessCredentials determines only
automatic applying or not applying received credentials.
