Renurpp,
I can see what your saying, but I think the phrase could be valid in some scenarios. I'm a pilot, not an ATCer but a lot of the ports we fly into (in a medium category turboprop) have ab-intio ultralight training taking place. I'm not going to caution everyone about wake turbulence, but if I see a situation where I think its warranted, then I'll say it. Just like I'll warn proceeding traffic of the flock of pelicans I see on final. Pick your audience I guess.
