Yeah...one day he'll become skilled enough that he doesn't have to do that...

I was just expressing my own opinion here...like we all do. If Mr. Matt wants to cut his engine on landing, it is his own choice. I prefer not to. Likewise, if he puts one of his big TOC planes into the dirt because of flying thru a wind shear over the threshold, dodging someone out on the runway, or something while deadstick, he can certainly better afford to replace his airplane than I can.
As far as the thing about showing how much control I have over my airplane and it's engine goes, I choose to display control of the engine after it's down and taxied back off the runway. Control is control, whether I exercise it in the air on final or on the deck.
I just see more reasons to leave the engine running than not to.

I don't really understand why this is an issue at all.
