WiFi On vs. WiFi Scanning

AwakeWoven

I've finally gotten the phone set up in a good place and think I understand much of the features.
However I still have some questions, that may help clarify if certain configurations are adding any benefit or just don't matter at all. Right now I'm looking at Wifi + Location Services.

WiFi can be configured to be turned off after short period of being disconnected. I think this helps with privacy because your phone is not then advertising by scanning for WiFi networks. However, the MAC address is randomized so this shouldn't be any issue anyway, even with WiFi left on. (Unless you've connected to a hidden SSID)
This setting leaves one likely to forget to turn WiFi back on when returning home, possibly eating up mobile data. This can be mitigated by the setting to automatically turn WiFi back on, which requires both Location Services enabled and WiFi Scanning to be enabled.
So my question is: is there any benefit at all to having WiFi disabled if WiFi scanning is enabled? (which happens while WiFi is "off") I may as well simply leave WiFi on at that point, no?

Thanks for any additional insight. I've read through the usage guide on both WiFi and Location Services but was left a little confused about why these features are included.
Also want to add I am incredibly grateful for the work done to make and maintain this OS, it's a godsend.

1) Keeping wifi on: someone could create a wifi network & password that is the same as one saved on your phone--your home, hotel, work. So your phone connects to their wifi network. Then they try and do stuff to your phone.
There's probably other issues that are rare to happen to the average joe.

3) Wifi scanning only lets services and apps turn on wifi momentarily to scan for networks. If you have location services use wifi APs to help determine your location then you would need both settings on. I'm pretty sure GOS won't turn on the wifi periodically to check if there's any saved WIFIs to connect to. It'd defeat the purpose of turning wifi off automatically.

Wifi scanning is a passive activity. You're not sending any radio waves. Just reading what's in the air.
