Funny, comparing Walt to Kosh isn't so crazy. Thing about Kosh is, yes, they used him sparingly, but they also didn't hold anything back and before he was killed, we got all the payoff we needed: We saw what he looked like, which was a big mystery from Season 1, and we learned he is one of the ancient races, another mystery, and we also saw how he tied into the overall story.
With Walt, we didn't get any of that. Nothing.
