Though technically true, it does encourage bad habits and requires timing, which is another "step" to maintain for a good consistent stroke. If you have a day that your timing is off it will certainly affect you hitting the ball properly.
I would also say this bad habit has a direct contribution to people not being able to follow well or they hit stun when they meant to follow. Being they do those shots less often they are adjusting their timing and usually drop their elbow sooner in the stroke causing the tip to raise and them to not hit low. I am of course speculating on this, but I rarely see it on people with good strokes that do not drop their elbow.
I rarely, if ever hit the felt during my follow through as my hand typically hits my chest before I could follow through enough. I guess that is a combination of being down low and not dropping my elbow/or popping up to create that clearance needed.
