Sometimes it's nice to see when the beacon was last seen, since the driver holds onto BSSs for a while, you don't know how long they've been in the scan list. If you only cared about the newest BSSs you could use this to ignore certain APs from the scan list. Would be nice to push this attribute back with nl80211 as well.
