I tried that at first and often there wasn't enough screw in the stud and it would strip out in it's hole as I was tightening it. The drywall in some places was probably 1/4" or more away from the stud.
I was referring to new drywall installation. Sorry.
We use 1 1/4 screws in new construction for 1/2 inch board. Using a longer screw in wet studs can cause the pops, as the wood shrinks to the center, and the screw is being held closer to the center. We use 8 screws per four feet of stud, and double the screws up, two inches apart, as was stated in another post. The second screw will show if it is tight. If the drywall isn't tight, the second screw will usually show this up.
If we have a problem area, we just use more screws until the drywall is tight. Very rarely we will have to take a sheet down and put a shim behind it. Much more likely in a rehab.

BTW, we usually let the framing sit for two weeks before insulating and adding vapor barrier. Where I grew up near ocean, there were some houses built years back that rotted from the inside out because they were built too fast and the moisture from the wood was trapped in the walls.
Two weeks is plenty of time to get wires and plumbing run, and let the studs air out. I know guys who crown all the studs to bow out on the same side of the wall, and put the most curved ones in the center of the wall when framing. Having one stud bow one way and the next stud bow the other way in alternating fashion is a sure recipe for a wavy wall that is hard to hang drywall on. Of course we cut up the worst of the studs for headers jacks and the like.
Of course, it is especially important to crown your floor joists and roof rafters up as well. If you have one crown up 1/4 inch, the next down a quarter, and the third up again, you could easily have a three eighths inch bow in your floor or ceiling. IMO, lumber is about the same as it always was, you just have to use it thoughtfully to get the best results. An extra five minutes here and there is all it takes, but is is easy to forget in the heat of construction. As they say, do you want it right, or do you want it right now ?
