My understanding of the seat situation is that the DOT considers the seat a significant factor in crash safety, and if a substantially different seat is installed, the manufacturer would have to crash test additional cars. The similar seats in the CGT are, I believe, the only option, so that model would have been crashed with them installed.

Crash safety is not necessarily worse with one-piece shell seats. As you wrote, they have just not been run through the additional crash test program specifically required by US leglislation.
