Honestly I don't get the excitement over this, the payload sticker is just a 'convenience sticker' anyway for people that can't do simple math. It's not like they have the GVWR or axle stickers wrong... those are the ones that matter. Those stickers didn't even exist until 2008-2009 somewhere in there.
I think people are sometimes misled by them. I know in the Truck camper world people use this sticker to compare campers (usually dry) and then think the can carry that capacity... forgetting that passengers, tools, modifications etc come off that number. That number also expects some of the weight will be on the front axle which is hard to actually achieve. I've weighed my camper.... it adds 150lbs to the front axle. You can still override your RAWR or tire capacity before you get to the magical cargo capacity.
Also as soon as you add accessories such as bumpers, tools, winches etc. then the sticker number is no longer valid anyway.
