Does Transferswitch Disconnect Neutral In Service Panel

That's exactly what must exist done . . . and that's exactly what we practise . . . every time. In addition, the grounding electrode connections (water, rods, etc.) must be moved to the new disconnect. The existing panel is now a sub-panel, and must be wired every bit such . . . every time.

That is referring to the generator's disconnect, not the house's disconnect/transfer switch. The requirement that everything downstream of the primary disconnect maintains neutral/EGC isolation is not changed.
Not switching the neutral ways that ane grounding electrode system can serve the house regardless of the power source. If the neutral is switched, each source requires its own grounding electrode organization.
Added: In fact, you're too supposed to supplant 3-wire major appliance circuits with 4-wire circuits, receptacles, etc.

I don't encounter why a neutral to case bond for the generator can't exist fabricated at the generator's disconnect providing the transfer switch is the generator's only disconnect. This aforementioned "service rated" transfer switch is also the only disconnect from the meter and therefore must exist the location of the one and just ground and neutral bail in the entire system. As long as the generator neutral/ground bond and main service neutral/ground bond are fabricated in the same bus bar within the same transfer switch enclosure I can't see how this would be a violation. No objectionable neutral currents would be able to travel through any enclosures or other exterior paths. No need to rout the generator ground conductor through the transfer switch but to connect information technology to the chief console's isolated ground bar as far as I can see. What If the generator was continued to the transfer switch via an armored cable? That would end up bonding the neutral/ground of the generator at the transfer switch anyway. Does this make sense?
