48v supplies are not practical for certified end-user products due to National Electrical Codes which limit the risk of electrocution on UL/CE/IC certified power supplies. Note, commercial Telecommunications equipment standards have a very different design market goal, so do use this DC standard already.
The current NEC code (pun intended) effectively limits most supplies to around under 32vDC in most jurisdictions for amateurs (equipment does not need retested in a lab, or signed off by a municipal ticketed EE.) Thus, a standard 24vDC (28vDC actual) equipment rail makes more sense in terms of design economics for the CPU/GPU buck-converters, and is indeed already very common to see in industrial/military rated hardware.
"speck of silicon in cables as well", Maybe... note USBC uses resister values to identify the plug initial behavior... but practically there comes a point where IT workers/hobbyists will have to know first-year ohms law again. At bare minimum people still need to calculate when the wall outlet power-limits are exceeded to avoid posing a fire-hazard in older homes.
I will spare you the xkcd cartoon about standards (and rants about ESD in USBC), but a power-requirement sticker would likely be just as effective for novices.
We all have mixed opinions on NVIDIAs silly GPU design kludges, but the industry has reached a sort of stagnation years ago. Cheers =3
