> A location with bad WiFi and good LTE reception (expectation: WiFi off)

Why are you not insisting that the OS simply disconnect on its own quickly in such scenarios? Why do you accept that manual user action is the right solution? If the phone automatically and quickly dropped a WiFi the instant it doesn’t support data, this problem wouldn’t exist. Instead Apple expects users to get involved in that problem and has now overcomplicated what should be a very simple switch.
