I'm on Android 8.1. When turning off Bluetooth the entire Bluetooth menu showing previously paired devices changes to just show the string "When Bluetooth is turned on, your device can communicate with other nearby Bluetooth devices. To improve location accuracy, system apps and services can still detect Bluetooth devices. You can change this setting in _scanning settings_[link to the associated settings page]".
I don't see how this is fooling the user. Its pretty direct in stating what's happening and provides a link directly to the additional settings.
