600W = 12V * 50A
the 12pin connector IIRC has 6 positive and 5 negative (or the other way around) and 1 reserved pin, so 5 pins on the narrower pole
50A / 5 wires = 10A, perfectly fine for 1.5mm² (a.k.a. 15AWG).
As to why not fewer, thicker pins, I'm guessing it's easier/cheaper to just add more of the wires you were already using.

Tell that to the 4090 connectors that have started to melt.
Sure, theoretically you could push the wires to be even thinner. The connectors are the actual weak link. But thin wires means small flimsy connectors. And we're already seeing what just 450w can do right now to the new connector spec.
