I referred to that thread but two posts before or so.
Meanwhile the thread has progressed and I encourage to read it to the and. I don’t want to say anything wrong.
The other part I wrote about the chaos in USB specifications and higher voltages is what I remember out of an article in German computer magazine C’t some time ago. Not even they were able to keep in the know of every detail. They wrote an analogously statement explicitly. I think higher voltage chargers are not very common, yet, but this won’t stay forever. Maybe they will be marked somehow. If negotiation go well and they don’t give to much power immediately everything might be fine. I am not a specialist. The fear or danger of those new cables was written in that magazine article.
