I vote against this approach.
If the controller assigns you a new frequency, and you acknowledge it, and change, I'd expect to check in on it as well, to establish positive communication on the new radio.
You were probably flying out of range on one radio, and he wants to be sure he still has communication with you.
That said, a nice and easy: "Bugsmasher 123X, level at ten thousand" does the trick.
Yeah, I don't get this. If you're in NYC class B, maybe keep it short to the extreme. But some of this sounds like someone loses a month off their lifespan for every word they speak.
