While I'm not necessarily against actually processing the Action frame
itself in wpa_supplicant, please note that the Presence Request frame is
a P2P Action frame and not P2P Public Action frame. The P2P Action
frames are much more specific to a group operation and I don't see any
problems in drivers handling them since they are more specific to exact
timing and parameters of the group and require synchronization with
low-level operations that are way below wpa_supplicant in the stack.
