Seems strangely Orwellian (in the sense of his politics-via-language writings, not the police-state kind of Orwellianism). It's a descriptive word that long predates these organizations, so it's sort of weird for them to retroactively take ownership of it. I can see specific, narrower terms, like Professional Engineer or Licensed Engineer, but engineering is just a description of a kind of activity that people have done for millennia, and an engineer is someone who does it.
