Very high chance of Apple removing it. Heck, AirPods Max have no power button. Someone at Apple is losing sleep over the fact people have control over the radios in their phone.
They changed it a few years ago so that they would automatically turn on again once you are at a different location, and if you wanted it permanent off, you can do so via settings app.
I found this to be an improvement in user experience because I would often turn off wifi in the control panel when I was on a weak wifi connection to force the phone to use the mobile network, and then I would forget to turn it back on when I went inside again.
This change made it so I did not have to remember to turn wifi on again.
However, I did not read anything about toggling in control panel not actually turning the radios off.
