Its actually a bug. Dwarves are now very eager to bring food and water to a dwarf even if the dwarf is not injured or confined at all. This was because previously there was a problem where dwarves would almost never do this, so the job priority was significantly increased.
Probably increased a bit too much, but I'd rather them bring a snack to sleeping health dwarves than ignore my injured dwarves to let them starve to death.
Ah, the point is, what generates the 'Bring Water' job? Not just hunger/thirst, because I had many almost-dehydrated guys doing steel batch smelting in an over*cluttered* blast furnace. So game checks for status anyway. But if it does, why not check if that dorf is either 1) injured/'Resting' 2) a criminal?
So, the point is not in how eager are dwarves to bring food/water, but in status checking at 'Bring water' job generation.
