Sounds like a great feature for improvising and also for playing in full keyboard mode. I've said a few times, that playing a piano is not like an organ. The piano music I've seen don't always use full chords, so the arranger won't recognize it. Sometimes the chord is arpeggiated (spelling?), so again the arranger won't recognize it. You don't always Hammer down full chords on a piano when the chord changes (even with both hands).
