I don't think it does, and this is something I asked Mohamed to add to wpa_supplicant. All the supplicant drivers somehow fill the driver capabilities max_scan_ssids, but this is not exported.

Hmm, I didn't think about it. But if sending an active broadcast probe request on a channel is as fast as sending the same probe request with an SSID set, then it's definitely worth it.
