@capngloval What I mean is that tracking devices have become mainstream.
Therefore, they are no longer "spy gadgets". You can be spied on by mistake (if somebody leaves one at your house) or on purpose, but the person may plausibly deny it ("I left it by mistake")
Therefore, in some environments, we will soon need to get used to scan for those devices (on top of "please shut down your cellphone") before sensitive activities.
