Just This Once, I totally agree with you. Once upon a time I was streamed ATC so spent a bit of time in towers as an asst. Notwithstanding the skills required to do the actual job, I was put off by all the superfluous mouth music that was seemingly part and parcel of it; much of it irrelevant to the crews and said for apparently little more than arse covering reasons.
Then there were the JSP318A phraseology comedians who kept themselves in a job by changing otherwise perfectly good official phrases once in a while - my favourite was the diktat to use 'cleared to land' vs 'cleared land', which reverted back about a year later.
