Oh don't worry. That wasn't me, it was the dealer. They invited me down a few months ago to view progress!
You said it doesn't squeak or rattle. I'd really leave well alone. And as far as I'm aware the dash is attached to what they described as a 'dash carrier' rather than just bolted to the bulkhead.
Scary pics though. That set up was so they could test drive with no dashboard. Hence the steering column held on with gaffer tape. They also test drove it like that but with no screen either.
