One of my children's schools wrote in its weekly newsletter to parents that, I translate, "the […] rules are by now quite intransparent. Of course we don't expect you to memorise all this. Please do ask us if […] or if you just feel uncertain." I am not making this up. "Of course" they don't expect people to learn the rules that apply to them, of course.
There's much to be said in favour of simple rules.
