I'm against this patch in mainline wpa_supplicant, it seems to be just
for your use case. Also, I think that your problem is already solved:
if you know that you only have one access point, why don't you use
scan_freq?  Excerpt from the demo wpa_supplicant.conf:

# scan_freq: List of frequencies to scan
# Space-separated list of frequencies in MHz to scan when searching for this
# BSS. If the subset of channels used by the network is known, this option can
# be used to optimize scanning to not occur on channels that the network does
# not use. Example: scan_freq=2412 2437 2462


For my usage scenarior (where I have a multitude of APs and might move
around) your patch would make thinks quite bad.
