Is there precedent for a rule like this?
If it is a common national rule, I might support it.
=======================================
FIA: Article 252 General prescriptions for rally cars. From article 7:
7.4 All body panels of the vehicle must be at all times of the same material as those of the original homologated car and must be of the same material thickness as that of the original homologated car (tolerance ± 10 %).
7.6 Any object of a dangerous nature (inflammable products, etc.) must be carried outside the cockpit.

CLASS DEFINITION:
10.2.B.5 Bodywork:

bumpers. Except for doors, bolt-on body pieces may

NASA Rally rules
3.1.3 Vehicle Eligibility
Vehicles eligible for events must be production based four wheeled passenger vehicles generally available for purchase by the general public. "One-of" vehicles specially built from the ground up for competition use is prohibited. To this end, the frame, floor pan, basic body shell, and firewall must remain original but may be modified for strength or to accommodate legal components. Exterior panels, including fenders, engine hood and trunk lid of hatchback must be present and visually similar to the original components.
3.2.3.3 Authorized Modifications
b. Exterior pieces (i.e.: all components licked by the air stream) must be visually similar to the original item, including bumpers.
=======================================
So,
for rally, it's pretty clear you can't remove exterior body panels, hoods, or trunks. Interior stripping is generally allowed in open class cars, but not completely in Production based cars, with some variations. So I'd say there's a fairly worldwide consensus within the rally community on those issues, along the lines Carl is going.
