> One of the primary drivers for this is the power delivery - imagine a scenario...
Not a USB engineer, but a quick peek at the BC 1.2 spec suggests the ball would have to be dropped on at least two additional fronts for the suggested failure mode to occur:
1.) The Charging Port device vendor for failing to implement any of the allowed shutdown measures suggested in BC1.2 §4.1.4; and
2.) the Downstream Port device vendor for failing to constrain current draw based on sensed Vaca_opr min = 4.1V (Table V) per ibid. §§6.2.2 and 6.3.1.
I can see how the knock-off cable would be toast, and depending on insulation rating, may potentially catch fire, but struggle to see how either the CP or DP USB-C ports would fry (considering they're both designed for a target power).
