Surely you are not arguing that replacing a service panel constitutes not touching the service. I mean, 230.85 is in article 230. In any case...
That's interesting but I don't see the relevance. While it's interesting that, by code, I might be allowed to repair knob and tube with knob and tube, I don't see how replacing a service panel necessarily constitutes a repair, nor does it address the OP's issue in any serious way.
Again, playing devil's advocate here, but I see no solid argument from these citations.
