Rinshan is magic because of it's rarity. To stack more tiles in the dead wall and increase the number of rinshan draws in a round is an insult to Rinshan Kaihou. The kan is more often than not a negative effect on your hand, and being able to pull a win from it surpasses almost all other feelings in Mahjong. Declaring kita has no tangible drawback and offers a free draw from the wall, and even increases the value of your hand. Do not think you can even loosely compare a slutty sanma rinshan to the beauty of a real Rinshan Kaihou.
