Delayed Wi-Fi and Bluetooth Scan Results

It seems that the Wi-Fi and Bluetooth scan rates have been throttled for battery and privacy protections. However, the last scan is not immediately shown once the quick settings pop up is drawn or the full settings app is opened. I must wait a few seconds (up to 5 seconds!) for a new scan to see network lists. I suggest the following improvements:

• A cache be kept of the last scan results and immediately listed when any connection settings page is drawn. I'd rather see devices that are no longer available, with a good chance the one I want is listed, than not see the one I want at all. If my device is falsely listed, manually connecting will trigger the series of aggressive attempts until the moment it becomes available or it timeouts. A timeout at this point isn't any worse than having to always wait at the start. A new scan result should be available before the failing connection attempt times out anyways. Timestamped results in the cache would also be nice to show how long ago a device or network was seen, specially for previous connections. Simple signal strengths too? I know this is how they are sorted, so the user already sees it. I just want to see how close they are. This would be helpful for the devices still with default random names or when more than one of the same type is present.
• Preemptively begin radio scans to have fresh results by the time the user gets to see them. This could be when the quick settings panel or settings app is opened (to some degree).
