They would say so in the same breath as expecting their Apple Watch and Apple Pencil to continue working on their iPhone and iPad respectively, and objecting when they break. Telling them they shouldn't expect Bluetooth devices to continue working when they turn off Bluetooth will make them confused and eventually angry with you; "these devices don't require pairing, or pin codes, or manual connection crap, or any of that nonsense, so they're obviously not Bluetooth, they just work". We know that's not true, but they don't care about that technical distinction.
If you're a normal user, you don't care about whether the radio is active or not. You care about whether you can easily disconnect from crappy Bluetooth devices, or whether you can easily disconnect from broken cafe wi-fi to switch to cellular. The control center buttons provided by Apple do both of those things, without breaking Apple's ecosystem of devices.
Is this resulting control center behavior optimal? Sure is for Apple users. Everything that's broken disconnects and everything magic continues working. Is this optimal for tech nerds? Sure, if they're Apple users, because they quickly come to realize how useful "disconnect from this specific SSID today only, but continue using wi-fi when I go home" is. Is this optimal for people who want to aggressively control their radios at all times? Nope, sure isn't, you'll have to go to the Settings dialog and realize to do so the first time, presumably having missed out on endless Device Paranoia 101 courses that explain this.
Turning off Bluetooth and Wi-Fi is something that most users do not require of their device, and do not want of their device. Those that do want this for some sort of specific reason are the extremely rare exception, and just happen to be in slightly higher proportion here at HN relative to the rest of the world.
