Good point with that last bit, I have a gaming laptop that comes with a big DC Barrel plug and power brick, which is essentially needed for playing games. However, it also lets you charge with USB-C which is what I use when travelling/doing productive work. I see no reason why this approach can’t be applied more regularly, as it increases flexibility and maintains compatibility with the standard.
I responded to someone else, but I have a gaming laptop that needs the DC Barrel plug for playing games, but also lets you charge it with USB-C (useful for traveling). That would meet the standard set forth, as it is compatible with USB-C charging.
