I had a closer look at those replacement cables and the power cable now includes a resistor in series which is certainly there for spike protection and the data cable had 3 wires removed black, red and blue. I don’t know about the blue but sounds like red and black was also a power input which if you want to protect the power cable, it would be counter productive to bring redundant power from a second input.
I’d say replacement is really not required but this little design improvement may be worth it. I would think all new printers may now include this change and I really don’t think it’s H2C specific.
