I wonder if this is yet another misinterpretation of what's "right" on airline ops that's been ported into the light aeroplane world.
I would hazard a guess and say you're not far off the mark. I have heard instructors before say things like "think like an airline pilot" and "fly it like an airliner." Looking back, none of those instructors had yet progressed to an airline, so knew not of what they spoke.
There was not a realization that a Cessna, Piper, or Tecnam is not an Airbus, Boeing, or Embraer. As both Genghis and Memories of Pax have pointed out, they have different approach profiles to transport category aircraft and, as such, are flown differently.
Heck, even within the transport category world a Dash-8 or ATR-72 has a different approach profile to a 737 or A-320 on account of the difference between turboprop and jet, so even my previous statement is slightly misleading.
