I'm not looking for counter-examples, just stating the way things
should be, not how things are (the Germans have a beautiful way of
expressing this: "Soll-Stand" vs. "Ist-Stand").  Your change moves us
further away from the way things should be. I hope you agree with
that?

Mind if I add a note, as below?

Ciao!
