That might be all well and good but what happens when the tongue is unweighted by road surface and more weight is shifted to the tires? Or, in some handling situations where individual tire load increases?
Having said that, I strongly believe that more margins in the ratings will result in a longer trouble free service life. How many utility trailers are running around with 15 year old tires because they're almost never loaded near their rating? (and then you see them blown out on the side of the road after they are heavily loaded)
