I have seen the kids picking this up from their MLB stars. Although I have not seen anything 6 inches long.  Maybe the pinky leather ties undone and both hanging at 3 inches each?  I do nothing here.

If it were 6 inches long as you say, I could adopt the "distracting in any manner" clause in the rules. 1.15 (a)

This post jumped to my mind last night, as I was at a District game. The 2nd pitcher on the home team had on his glove the pinky retention leather straps were untied and dangling free.

At the wind up, and the set position they were not visible to the batter as they were laying against the glove. When they became visible was when he pushed the glove toward the plate, and at that time a batter should be looking at the release point of the other hand, or looking for it. So after watching for 2 innings last night, I think that there was no distraction. BUT, these were not 6 inches long, nore like one was 3.5" and the other 3".  I wouldn't waste my time with this as being a distraction.
