That is not how standards work. Standards are standards because they are standard. Also, just use usb c, it does literally everything you need.

Edit: the article says theres a usbc compatible version, idk how thatll work but well see. Other thing, the article says hdmi doesnt have power but there are active devices that dont need power, how do those work then?

Edit2: yup i was right hdmi can cary 0.25 to 1.5w depending on version.
