I don't think one excludes one or the other. Nothing is absolute, may be why this topic will never die.
In my honest assessment of reading a lot of the views/opinions; I concluded axle weight is mostly like only going to be relevant if you are
#1. Hauling a Towed
#2. Have different tire than what was OEM specified.
#3. Knowing you are loading your RV a lot more than normal, like exceeding passengers and/or luggage, or using the RV as to save money versus renting a U-Haul truck or trailer to haul some heavy stuff like Gold bars 
.
Case in point, weight is NEVER going to be factor for me.
Why?
Because I have the Goodyear OEM tires and based on Goodyear Mfg specifications,
my tires MUST be at least 80 PSI, at the same time based on the same Goodyear chart;
85 PSI coincides with the Maximum weight rating permissible on my Ford Chassis based on RV Manufacturer Specifications. So the Engineering works out in between to 82 PSI; which is what my Yellow sticker says. So my Yellow sticker is 100% correct, and I am also following the weight guidelines of Tire Mfg. So when I check my air pressure, if lower than 80 psi, I add to 82 psi. If higher than 85 psi; I lower to 82. I have never had a weigh, may get one one day, but in my use case, I do not need a weight to figure out what pressure to inflate my tires too.
