I can see almost no situation in which the benefits of having a plugged in camera or mic I do not know isn't always on outweigh the costs, even if the cost is "just" mental complacence with surveillance.
If I need peace of mind away from home, I can simply plug in a webcam or connect the otherwise-airgapped security system to the network while I'm away. If I want a hands-free mic, I can buy one with a power switch and connect it to whatever setup I need it for.
If amazon releases hardware that makes it verifiably possible to have such setups, more power to them I suppose. But as likely they won't, as they prefer "all-in-one" solutions that give them "last-mile level" control over how their devices get used, I will probably never buy such devices from them.
