If it helps then use it.
I'm not a great fan though.
If the arms hung straight down from the shoulders then perhaps haviing the eyes over the ball may help as that would encourage a straight back straight through swing.
However, there is an angle, preferably at the elbow which means there's more likely to be slight arc to the swing.
As long as the golfer can present the putter face and swing path to the ball in a consistent manner I'm not fussed how they do it.
I do know however that the fewer moving parts you have when putting, the easier it is to be more consistent.
I agree.
It adds to the fun to chase a 3footer with your right shoulder every now and again though
