I've thrown more coin batteries in the trash and battery recycling bin to more than make up your imagined sensors and devices with internal batteries going to the bin.

In fact I've had no failures of the internal batteries of any of my cycling devices. Even those that are more than 10 years old. I acknowledge that some people have had issues with their internal batteries on their devices. But I'd be willing to bet that those are still far fewer than the amount of coin batteries that get tossed. And even though we do toss them in battery recycling bins, I still see too many articles suggesting that the coin batteries aren't being recycled as it cheaper still to use raw materials. But hopefully, I'm just finding dated articles that don't reflect the current times.
