The userspace is welcome to keep a pool of all APs found by any scans,

Drivers need to keep a reasonably complete list of APs internally for
association anyway. You don't want to have to do a full scan just to
associate if you have results from 10 seconds ago that are still valid.
This is not an issue for orinoco cards, as the firmware selects the AP to use independently of any driver scanning. The requirement to use ap_scan=2 means that wpa_supplicant doesn't need to look at the scan results either (except maybe to verify the configuration matches).
Furthermore, drivers need to keep cached results so that two processes
can request results of a scan after the scan is complete.
But this does apply to orinoco.
