With the pre-release of 1.9 they added waterlillies. In my experiments with them you can harvest them but you can onyl replant them in 1 block deep of water (or on the edge of block with water). This could allow for waterbased farm plants to be added such as rice and taro, (more than likely rice) or even allow sugarcane to be planted in shallow water. You could require mud/dirt blocks, and a waterblock above it (a full block, not a flowing block). The rice/plant would planted in the ddirt block (maybe requireing it to be tilled into a farmblock) and have shoots just barely jutting out of the water and slowly grow.
But to rice I agree.
