I think this one has always appeared to be a bigger problem than it really is. When I became CEng I had no-one working for me, and the same with several people who I have supported through CEng. You would expect a CEng to be taking management responsibility for significant work, but that doesn't mean they have to be a line manager.
CMgr is management recognition (I must do that one day), CEng is engineering leadership recognition.
