The meta protocol exists! Sort of. Check out the USB-C specs, which tried to answer a ton of this. It’s taken years for power delivery to reach the point where I don’t feel compelled to carry a USB-C power meter to check cables and chargers in the wild. My Switch still requires some out of spec signaling to charge/dock properly.
Meanwhile, half of the stuff I get off AliExpress only charges from A to C cables due to a missing resistor.
I don’t think the markets (yet) incentivize implementations. Like how when my mortgage gets resold, autopay will only transfer over if it’s once a month; anything more complex and I have to endure a new account setup and a ton of phone trees. Same with paperless settings. The result? I just live with the MVP.
