> One cable doesn't do everything
Well, seems like because physics™ it's hard to do both 420W charging and 69Gbps data over the same cable. And also people want thinner and cheaper charging cables. It's still better to have a unified connector and different capability cables.
> most cables get it wrong to a dangerous degree
That was the case in the early days. These days it's getting hard to find bad cables.
> negotiation is more complex and expensive to implement as well, even if you're only doing a low-capability device
No need for negotiation in a low capability device. Two resistors. It's not rocket science. Raspberry Pi did screw up and use one resistor but they made that mistake so famous that everyone knows not to repeat it now.
