Nope, you're right. wpa_supplicant.conf(5) calls it out clearly:
scan_ssid
SSID scan technique; 0 (default) or 1. Technique 0 scans
for the
SSID using a broadcast Probe Request frame while 1 uses a
directed Probe Request frame. Access points that cloak them-
selves by not broadcasting their SSID require technique 1, but
beware that this scheme can cause scanning to take longer
to com-
plete.
though obviously you need to know to look there. Thank you.
