The list of nearby APs updated by Android when this option is enabled is available to Tasker, so there's no real benefit to using the "toggle wifi" option in Tasker if your version of Android has this feature and you've enabled it. I think what Pent is planning is to look for this setting in Android and, if it's enabled, ignore Tasker's "toggle wifi" option since there would be no benefit to turning Wifi on, but if the setting either doesn't exist or is disabled in Android, then Tasker's "toggle wifi" option will be used accordingly, turning on wifi (or not, depending on the setting) to refresh the list of nearby APs.
