Not two different objectives. Not at all.
Set up the WDH first. This implies doing so correctly. If there is too much rear sag, that means the WDH isn't set up correctly.
K.I.S.S. Keep it simple stupid.
I have to disagree with this statement. Every combination is different - some truck springs are softer in the rear than others. To throw a blanket statement out there there saying too much sag means the WDH isn't set up correctly doesn't work.

It sure does. WDH works with soft springs and hard alike. You wont find anything in text to back up what you're saying because it contradicts what WDH is designed to do.
That said, soft sprung trucks and SUV's may see a reduction in ride height at the front in order to get the rear sag in spec, contrary to book specs. But WDH will absolutely correct rear end sag when set up correctly. Again, that is what its designed to do.
If you have too much rear sag with a WDH and adjustments don't appear to change anything, then your weights are higher than what you thought and/or you have the wrong class WDH to handle the weight.
Your last sentence in this quote is exactly what I'm talking about. You threw a blanket statement out there, and now you've modded your statement with an if/then statement. You didn't have that in the initial statement. I wanted you to see that such a blanket statement doesn't work.
There is no "rear sag to spec" in WDH setup. You set the hitch up to transfer weight back to the front axle and TT axles. Rear sag does typically change when you do so, but you aren't adjusting your setup to achieve a specific sag in the rear. As mentioned above, you target 1/2 the difference of unloaded front height, and loaded front height for your WDH, and the rear goes where it goes. This is how Ford specs WDH setup currently, and I believe that is the case with Chevy and Dodge as well. It might go back up an inch, it might move 1/16" of an inch. What the back does is Irrelevant. The front height is what you are working toward.
