What we don't know is if the side curtain deploys the same way each time - regardless of if the seat airbag deploys. If the trick the system into thinking the airbag is there, will the rest of the system deploy all of the other airbags as if that seat airbag deployed - or if it didn't?
Good point about the windshield as well as the fewest people would consider that a part of the safety system and why it is vital to change a cracked windshield.
The airbag system makes literally millions of calculations prior to a deployment to answer one question "Will I reduce or avoid injuries if I deploy?"
Some vehicles take seat position and passenger weight into consideration. While the 4R doesn't do that, it does include active headrests to reduce whiplash injuries.
What else does the airbag system take into consideration and how will a swap affect the deployment of the rest of the system?
Manufacturers make the theoretical calculations when they decide on a a change - then they crash test the cars to validate their calculations.
We don't have that luxury, so we need to consider all of the consequences. While we can't consider unanticipated consequences, we can anticipate unintended consequences.

If you look at Porsche within a model range there are up to four or five seat options you can get for any particular build, so within a family of vehicles there would have to be some wiggle room, I would think.
As long as the seats are wired similarly to talk to the truck… That is.
With the fifth generation I would assume that would limit you to the GX.
