Captain Dart,
I work here and understand, to a certain extent , what you are getting at.
My particular favourite is a change of QNH on the ATIS. I make an All Stations broadcast. There are multiple changes, including the QNH.
My understanding is that I then have to make a directed transmission to any aircraft I have previously given the QNH to. Sometimes it is like pulling teeth to get the pilot to read back the QNH.
I know that the pilot knows the new QNH, however I HAVE A REQUIREMENT to get a readback. It is anal but that is what I am required to do. You can't argue simple common sense with the powers that be. They WILL make an issue of it.
Captain, no use arguing with the poor mumpty on the headset, they probably agree with you. Welcome to the Galapagos, tie up the Beagle over there.
