I think is impossible to standardise everything. You can do it only with products with limited use cases, like Bluetooth devices, USB HID devices, some "standard" USB devices like cheap mouses, sound cards, disk drives, or WiFi NICs. I won't ever happen a GPU standard in a short or medium time, because deciding how it would work were giving their R&D to the competition, and AFAIK, Nvidia, AMD, and Intel have totally different types of architecture. Printers maybe could have some kind of USB standard, but I don't think the different printer making companies are willing to do that, the same happens with some kind of "gaming" devices. That would mean not showing ads of cartridge or other products and letting the users be more outside of their "ecosystem". QMK keyboards are a honourable exception to this btw.
