I agree the data is only strong from the relative viewpoint of this is what the FDA wanted and this is what they got. Of course the FDA is well-known for sticking to their goalposts!
The discussion of transgenic stuff and implications will happen anyway. I would rather it happen in a public forum rather than within the FDA itself amongst bureaucrats, especially risk-averse ones.
While I think the overall approval chances are strong in either case, it becomes stronger if there is a public discussion rather than private.
