Well if you have the Find My Device functionality enabled, not being able to turn off Bluetooth (and WiFi) is a good thing, since a thief cannot disable location deriving and reporting features by turning them off.
I don’t think those are connected…or at least it would be silly for that to be the case. Say your laptop was stolen when your BT was off for some random reason - does that mean you won’t be able to find it?
Yes but does it matter if your BT is turned off _visually_? The device can still send data.
Besides, receiving consumes more power than sending, theoretically Apple can just shut off the receiving part and send intermittently (every 2 sec or so) and achieve very minimal power usage.
Again, this is just speculation, I’m genuinely interested in the details.
