I admit it is somewhat unlikely anyone will ever attempt to apply for a passport with a trusted traveler card as ID, but it potentially could happen.
I can think of one hypothetical scenario. Anyone who has lost or damaged their passport must submit a new (not a renew) application for passport in person and present photo ID.
If the applicant was (for example) a US citizen who does not live in the US and has a damaged passport, it is entirely possible they would have none of the acceptable primary ID documents (like state ID or driver's license) yet carry a trusted traveler card.
In this case I would show my GE card and see if that is acceptable. I don't think simply because the linked passport becomes damaged that the GE card suddenly becomes invalid federal ID.
