This is the key point. I imagine the stakeholders here do not think the weight software is that critical, when in fact it could be. This is a common issue with complex systems.
Even though the software does not directly interface with the plane, its outputs are used to make key decisions on takeoff. Normally, there would be a large margin of error allowed, but in this case, due to the desire for max efficiency, the behavior of the aircraft is sensitive to the outputs.
The solutions are to (1) go back to having a large error margin, which of course should be cross-checked for sanity by the pilots, or (2) consider that the software is safety-critical, and should meet the same quality standards as the in-built flight systems.
