Going off topic a bit here, but its Monday.
I think building a wheel set to handle all ranges is a big ask. I would not want to buy a wheel set that would work for a 400# rider for a 140# rider. There is too much extra material to handle such a range. So while some do not like to buy parts that have a max weight recommendation - I prefer to buy such parts. It says the manufacture was paying attention to who they are selling to.
I've ridden 24 hole on the front of my 400# tandem. It worked, but it was not a good idea.
