I have never been tempted. The way I play and hold my flute it would be more of a hinderance than a help. That finger always seems to need to be ready for a tap or a roll so holding it down would slow me down. I was taught long ago that I should be holding my flute with a minimum of grip for a maximum of flexibility to ornament. "Spaghetti fingers" was a phrase I remember. My chin, my two thumbs and an occasional imperceptible counter weight from my right little finger when needed seem to do the job of holding my flute. Stabilizing the flute is an act of balance not of grip. My first teachers taught me that my flute should be held so lightly that someone could easily knock it out of my hands while I was playing (not that I'd want them to.) I do feel free to grip a bit tighter in a crowded session when I see someone squeezing past with two pints and a violin case. But I let go when they've passed.

I see a lot of new players with the death grip on their instruments. It makes it hard to ornament and easy to injure your hands.
