I will not deny that implementing swimming is a complicated matter, but it has already been done, in 1.7.10 at that. So it is definetly possible, as proven by the Smart Moving Mod. I think the ability to swim, to move naturally underwater is one of the best additions to the game and makes a lot of sense, compared to the current "walking and water-treading" technique.
