Engineering wise -the equalizer in a leaf spring trailer suspension only function is to allow independent axle articulation as the axles move through suspension travel range.
Remember, that a typical leaf spring trailer suspension only has 2-3" travel from the neutral position(frame level)-compression or rebound wise.
Being nose high takes the trailer suspension out of the neutral position and compromises the suspensions ability to absorb roadway irregularities.
Being nose high is not really about the weight distribution, but about the compromise it imparts on the suspension system working properly.
Agree with everything but your opening statement. If the only goal was to allow independent axle movement, there would be no connection between the leaf springs, each axle would have a setup like typical single axle leaf springs. The equalizer does allow static and dynamic forces acting on one axle to alter the eye to eye spacing of the other spring and therefore attempts to balance the forces between the two axles.
