Certainly. They've already changed it such that "turning off" Wi-Fi or Bluetooth from the Control Centre doesn't actually turn off the radios, it simply disconnects any devices, or disconnects from any networks the device is currently connected to. You have to turn on Aeroplane Mode or go to the Settings app to actually turn them off.

Even then they could still be on. You have no guarantee

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.
