Agree with you 100%, espeically if you're a NR spending several hundred or several thousand dollars on a hunt. Last fall I zeroed my .308 at 200 yards and practiced well beyond that with a range finder, estimating bullet drop and holdover with the reticle using the method you described. I killed my bull at 80 yards fortunately, and didn't need to worry about holdover or kentucky windage.
That all being said, I think we can always improve our shooting technique and skills to be better hunters. After reading various threads on here including the .223, .243 vs. .25-06, etc..., I learned a lot, and acknowledged my own personal opportunities for improvement. The SWFA scopes I referred to have dials and reticle hashes. If a guy doesn't want to fiddle with dials, he can very easily use the reticle hashes for the same effect and level of precision. This is better than simply "aiming a tad bit above..." because you have deliberate aiming points based on your trajectory. This significantly reduces estimation and guesswork and leads to better hits and cleaner kills. This is especially true if the animal isn't perfectly broadside and the normal vital zone shrinks in size.
This fall I'm taking my 17 year old daughter on her first cow hunt. I swapped the Burris for the SWFA, because I want her to be absolutely confident in her shot placement, even if we need to stretch the legs of my .308 to 400 and beyond. I want to control as many vairables as possible and empower her to maximize her accuracy. Speaking for myself alone, giving her deliberate aiming points or being able to dial the scope at longer ranges will increase her odds of success vs. aiming a little high or God forbid having to aim over the top of its back.
