what's in the "AIM" is completely irrelevant
Don't you think that's a rather narrow view to take? The original poster may well find himself flying in the US, and other countries, where the AIM is the Radio Bible. Lufthansa, for example, use the AIM phraseology irrespective of where they fly, as do all those North American pilots flying in all the same airspace as the rest of you.
Tolerance buddy! It's a cool attribute in a pilot.
