Well, yes. It's a spectrum.
Once you reach third to fifth level you pass what I would consider to be mortal limits. While someone in plate and shield could survive being hit with a sledgehammer by someone of great strength, after a point it doesn't matter how much the force is distributed after the third or fourth strike.
When push comes to shove, we're playing a game. I feel there should be enough realism, simulation, whatever so that if I'm operating within realistic bounds I can appropriately extrapolate consequences of my actions. If I fall off a cliff I'm going to die. However, once I have made a pact with the sylphs of the Grey Mountains, I can cast feather fall and I'll be okay. I really don't see this stance as some sort of heresy that Blue, Hussar, and others seem to.
Or, in other words, this.
