On that note, why assume that the manufacturer would not do the opposite: feign helping the spy agency by giving them a compromised ROM and then substituting a secure one on the real product. In either case, we are assuming the company would try to supply different bodies with different ROMs.

It is not that the mentioned scenario is impossible. It is that it just seems like too much effort to be made by a company that has no benefit in such duplicity.
