Sadly true in too many cases.
I was one of those pedants who used to bust peoples' chops about that. It's bad radio discipline. Roger, Over, Out, WILCO ... a lot of terms have precise meanings if one bothers to learn what one has been trained to do.
A lot of our ship based air controllers got in the habit of using "roger that" but I am ten years out of date. I would hope that someone would have tried to clean up the airwaves, though maybe enough pedants are not around to have enough impact.
