The RTF phraseology you describe has been in use at Manchester for at least 5 years. Well I say in use, its in the part 2!
It is slightly different, however, e.g.
"c/s holding DAYNE, descend flight level 90"
As fot the "climb FL... set altimeter 1013" that's just crap! IMHO
There are, I believe, far more important issues that would have a positive and instant benefit to air safety.
