A lot of interesting new systematic complexity. Cards are now expected to read total system load telemtry pin & throttle themselves semi-intelligently, in a non-cooperative arrangement with other power consumers. Good luck with this pcie.

In my weird world I think we could/should just make pcie cards expose a usb root complex, with a usb power-delivery device plugged in. you'd need cooperation with the usb committee to get amps beyond 5a, to scale to- hi im a gpu, can i have 20A at 12V? then the psu knows how much juice it's expected to ask.

usb-pd is pretty great with how devices make bids, negotiate to try to get what volts and amps they want, & make up alternate asks if they get denied.
