There is a limit to the amount of realism needed in a TES game. Certain aspects of realism can really damage the games enjoyability. Think about Khajiit. Why would a cat-like creature, that depends on four legged running speed need to walk on two feet? There are certain things that may not make sense, but it doesn't matter. Basically, a permanent water breathing effect is better. Perhaps a longer breath meter would be nice, but, and I'm no expert on programming, but it may be a lot harder to implement, and it may not warrent all the extra development time.
If a differantiation was ever made between "able to breath underwater indefinitely" to "able to breath under water for hours at a time", perhaps our answer would be more clean cut...
