I am sure that the list of devices needs to be expanded.
Synthesizers, trimmers and other portable devices still allow for a variety of different cables. That is, the user is forced to keep at home both a mirco-USB for a toothbrush and a separate DC for a razor. This is, at least, not convenient. And when an outdated wire fails, then you also have to look for a replacement. So at a time when there are many high-quality modern USB-C cables, you are spending money on an outdated cable that is rarely used.
If such a law is implemented in the USA, it will have a positive impact on the ecology of our planet.
