I'm sure we all agree on the basics of our subject. What I'm drawing attention to is plain poor practice and I've outlined a few examples to illustrate my point.
If you think extra waffle is ok then we disagree. I gave examples including unneccesary offering, wasted calls due to 'crossing' etc etc
Brevity does not mean poorer comms it means better comms. It's not the case that more words +repetition makes communication better! Extra uncalled for stuff multiplies over time leading to blah!.
Your point about being cleared/ reading it back is correct.
All I'm saying is ONE clearance = ONE readback. Which is what you said, I think.
