Yes, doing things right will take a whole arc. I wholeheartedly think that Improved Farming should be implemented, but the problem is that it will take a long time, and I want better farming right now. The other problem with improved farming is that is sort of relies on Mass and Volume being implemented, which would take a lot of work as well.
Well, a LOT of things in Dwarf Fortress are going to take a long time to be done right, and Toady doesn't really seem to be the type for half-assed jobs.
Toady just doesn't ever seem to make the "short, simple" changes that people keep trying to suggest as stopgap solutions. He either goes all the way with the long, thorough solution, or he puts it off until he is ready to do the long, thorough solution.
I talk about some of the elements of Volume and Mass in the Improved Farming thread, but Toady isn't going to follow my suggestion thread exactly, probably not even closely, and he may not follow it at all.
Beyond that, Volume and Mass is creeping into the game already. Look at your large pots, and you'll see they have a [CONTAINER_CAPACITY:60000] token in them. The game doesn't yet track the volume of items as a part of container capacity, but Toady is obviously gearing up to do it eventually.
