Thank for the reply, to follow up:
I. "never meant to turn off Wi-Fi" - it was meant to turn off the Wifi, until recently that's what it did. Even the macOS turns off the Wifi when you press the turn off wifi button.
II. "There's no real benefit in turning off Wi-Fi entirely" - there is, one huge plus is the battery (which for me it's important, if I want to not always track the battery level and stay as close to home as possible in case I need to recharge the battery again, why would I want to have the wifi on if I already turned on the mobile data while being outside). And, I see you also said that's used for location while turned off, so, that's extra battery drain while I'm outside and I need to have the battery lasting as long as possible....
Secondly, the security, which is a security concern having the wifi always scanning for networks (that's what it does while it's on and not connected).
III. " And having it on, aids in different phone functions including location even if not actually connected to a Wi-Fi network" -Do you want your phone to always track your location? Even when you sleep? Also, when I'm outside the Maps app it's doing a very good only by using the mobile data, great location accuracy, I don't see any reason to put extra weight on the battery for something that's not needed.
IV. It's just simply irritating to have the iOS doing something else than what you're asking it to do.
