The question is: does flying into the wind decrease the list of hydrodynamic drag problems to the point that they are no longer problems?

It can. But, it will shorten the feeding runs, in some cases, drastically, because it reduces the groundspeed -- unless some form of energy is added to the equation (a uniform wind doesn't add that energy -- thank goodness winds usually aren't uniform, and they lead to turbulent effects that the animals can utilize).
