Yes, that crossed my mind too. However there's currently no way of
telling a driver how long it should stay on each channel during scan.
We also wouldn't be totally piggy-backing the overlapping BSS scan
since ACS can do a couple of scan-cycles (unless we decide not to, and
simply do a very long scan on each channel once).
But yeah, using scan seems certainly simpler and would make it easier
to add BSS-based ACS in the future.
