You can think or rationalize the legal meaning of GVWR anyway you want, but I contend that the GVWR on that FMVSS sticker on your door is a certification as to the "MIMIMUM SAFETY" standards for performance of your vehicles braking system and exceeding that number means you are "NOT OPERATING YOUR VEHICLE IN A SAFE MANNER".

A few years ago, I tried to find out what the law said in pretty well every jurisdiction in the US and Canada about vehicle loading. In every case, I found that there is
NO reference to the manufacturer's GVWR for any vehicle.
I'm not trying to persuade people to violate that rating, I'm just pointing out that there is no law that I could find (and there were a few jurisdictions that
used to base their laws on the manufacturer's GVWR but had rescinded those laws) that used the GVWR as a base. All I could find was vague references to tire ratings. If the load on your vehicle exceeded the rating of your tire(s), you were considered to be operating an unsafe vehicle. As long as you didn't exceed the tire rating - or that the vehicle was loaded in such a way as to render control-ability questionable such as a seriously tail heavy vehicle making steering ineffective - then you were good to go. It didn't matter if you exceeded the GVWR of the vehicle at all.
