I think the thing that would let me stomach it is 1. Only legally mandating it for consumer devices / sold on the open market / commercial entities manufacturing it, or whatever the sensible way to structure that sentiment is, and 2. USB supports negotiating higher power settings, so you're not artificially limiting what's possible, just enforcing a safe worst case. If you need some USB connector that carries a kW you can theoretically still do that, you just have to not default to putting 100+ volts across the power pins the moment the thing is plugged in.

- yjftsjthsd-h 3y agoI thought it worked fine with devices that had never been updated because you start from the very oldest spec and the lowest power and then both devices have to negotiate up? I mean, sure you won't get better performance or power out of an old device but it's at least safe which is good enough for me, and for bonus points it's likely to work at some reduced level.
- verandaguy 3y agoYup, that's how it works, but you unfortunately can't retrofit out-of-spec devices like the author's to be within spec at scale.
