if you take note of the PCB cutout of the pins, theres a small unassigned stubble in front for the purpose of disallowing the card to plug into a PCI slot.
this stubble could theoretically be used for the extra power pins.
Agreed. They ought to revise the slot to carry 150w. That would allow *most* AICs to not need any supplemental power whatsoever, and high end GPUs and such could easily get by with a single supplemental cable.
That said, the change should be a lengthining of the slot, rather than adding pins to the key notch. This will allow newer cards to continue being used in older motherboards rather than the other way around, which is prefrable, as that is the direction most users will move. (people will be putting new GPUs in their last-gen mobos, for a few years, but almost no one will ever put an old GPU in a new motherboard).
It could also allow *limited* compatibility even in the case of new AIB in old mobo, so long as the area where the new power pins goes is not physically obstructed on the board. The first few years of new AIBs would require the option of being powered via the slot OR supplemental power in order to compensate for the potential of plugging a new card into an old board, but that's an easy comportmise that will resolve itself naturally after a few years.

No the problem is backwards/forwards compatibility. By adding more pins *anywhere*, they would be forcing the loss of compatibility in one direction or other going forward. Personally I say that's ok, as its been a VERY long time since the physical slot has changed, and no one in their right mind is going to be using 2003 AICs in a 2021 mobo or vice versa.
