Surely this is why we should have caution, because if it escapes it's very hard to control. This wheat was never commercially sold, what if the reason for that was that it was a danger to human health. Do you just want it popping up anyway?
Well that's not the reason, the reason is they are testing it out and seeing if it expresses the desired traits. They do extensive testing and sequencing in a lab before it even enters an open field.
