This idea is something I've always sort of had, but some instructors clarified it for me and really gave me some terminology - "shot cones" - to clarify and solidify my thoughts. To be clear, what I'm about to talk about is NOT a Stack and Tilt principle, but simply a "good golf" principle...
The idea is "shot cones." Virtually every golf ball we hit curves one way or the other, and on the PGA Tour 95% of the full-swing shots a player hits are his "stock shot" with that particular club.
A shot cone is simply a way of thinking about the boundaries of the start path and finish point of the golf ball. That is to say if you drew a line along the direction your shot starts and then draw another line from where the ball sat to where it finished up, you'd have a triangle, wedge, or a "cone."
One of the keys to playing consistent golf is to keep your shots within your cone. This means that if you play a push-draw, the ball starts inside the right edge of the cone and does not draw past the left edge of the cone.
Here are some examples of shots that stay within the cone and shots that do not:
In the top row we have a draw that starts on the right edge of the shot cone and draws to the left edge. Then a draw that starts on the same line and doesn't draw quite as much, a draw that doesn't start as far right and draws back to the left line, and finally a bit more of a push that simply doesn't draw much at all.
These are all acceptable shots and all the kinds of shots you can play for. If there's water right of the flag, you simply put the right edge of the shot cone on the flag and, if your ball stays in the cone, you'll be safe. (The flags are simply there for illustrative purposes - the left edge isn't always on the flag for a draw, per my last example of water right.)
In the bottom row we have a ball that starts on the right side of the cone and then over-draws. Then we have a shot that would turn out fine but which would indicate something's goofy in your swing - a shot that starts right of the edge of your cone and draws back. Then we have a pull-fade in our push-draw shot cone, and finally a push that is outside of the shot cone.
These shots - the ones that leave our shot cone - indicate that we've done something goofy in the swing that's going to cause problems. Shots that leave the cone are the shots that lead to big scores, trouble, short-siding yourself, etc.
It simply comes down to predictability. If you have a cone and your ball is always within that cone, you can play good golf and SCORE well. If your shots are leaving the cone at any point, you're far, FAR less likely to score well and you likely have something funky going on with your motion.
Some good players (and some PGA Tour players) I know keep track of these kinds of shots... they'll consider a good round one where zero or one or two shots leave their cone and a bad round one where three or more shots leave their cone... I think it would help players here to do the same.
For higher handicappers, you'll have a larger cone. If you play a pull-slice, keep every shot in that cone - you know it's the push-slices and the pull-hooks that get you into trouble. For lower handicappers, work on reducing the size of your cone and still keeping all of your shots within it.
