Could someone tell me again how the latest/newest drones compensate to keep constant application rate depending on ground speed affected by head/tail winds?

2nd question.....if they are able to compensate for the ground speed variances would it not be prudent to apply a field flying directly into head & tail winds vs flying with cross wind and having the product stream angle off to the side while losing the proclaimed downward force of the rotors? I assume the drone doesn't care which direction it's flying and wouldn't it be more prudent to fly direct into a headwind/tailwind situation?
