This feels like one of those small innovations that will become a marker of quality once somebody thinks about them for a while. Someone will figure out how to make the perfect indicator visible in a dark-ish environment without emitting much light otherwise, or some other way to confirm something is charging and it’ll become the way you can tell which electronics are expensive. I, for one, can’t wait. My fiber box is wrapped in so much tape you could drop it from a tall building and it’d be just fine.
