Agreed. Though any evaluation system would HAVE to be 100% confidential. Why?
Because many H.S. coaches are afraid to evaluate an official honestly, for fear that his/her colleagues will exact retribution. If soccer is anything like basketball, coaches can blackball an official or two. Most basketball coaches DON'T use the blackball for precisely that reason.
I personally find it more offensive when an assigner/evaluator stands on the sidelines during a game involving his coach/son's team.
