Let's hope they implemented them rotationally symmetrical, even though
USB-C is not. (-:

This would mean they are likely unbalanced and not individually
ground-shielded.

Anyway, using balanced audio for modular would be pretty silly.  You'd need

Not for the outputs, they could be impedance balanced like often seen on
other audio equipment.
