I was talking about pre-4 Pis, they have USB 2 and the specification
on that (except for some 'power only' ones, which the Pi's USB isn't)
is a maximum of 500mA.  So cables which are perfectly OK for the USB
2.0 specification don't necessarily have to be able to carry the
current required by the Pi.

I agree that with the advent of USB C/3 on the Pi 4 the Pi is well
within the specifications for those cables/interfaces so cables
conforming to the specifications should be capable of carrying the
required current.
