Aside from the scare bolding, the electrical situation isn't as bad as it is made out to be. Electrical separation can be managed in a lot of ways besides physical separation.

I expect this one is: If there is a fire in the tail and the insulation is burned off, and then the remains of the wire's insulation comes off and then if the wires are moved so a power wire from something contacts the drive power wire for the trim motor, then couldn't that cause a problem? Or - suppose a worker just takes a knife and shaves off the wire insulation before installing the wires exactly where they go into a clamp, but arranged so they almost touch (so it passes functional inspection) and then after years of vibration they do touch, couldn't that be a problem?

I'm more perturbed by the allowance of post-acceptance part alteration that isn't called for in the engineering drawings. That's a practice that needs to be dealt with harshly.
