When spelling, every letter in the Alphabet is pronounced by a single syllable, with the only exception of W being pronounced "double-U". (Fun fact, in German it's approximately pronounced like the "ve" in very, but in some strike of cosmic justice Y is pronounced "Yps-e-lon") Why is that? Is there any at least semi-officially accepted one-syllable alternative pronunciation of W?
I checked some related post, e.g. this one, but they are more concerned with the "Why?" instead of the "Why not different?"

Sometimes if a university is located in the area which name starts with W, such university is called informally U-Dub.
This is the only case I can recall. But I don't believe that using "dub" instead of "double u" is common (or even exists) in any other context. Though I'm not a native speaker.
Here is quote from Wikipedia:
Also, in Wikipedia, in addition to "U-Dub" example, it is mentioned that Volkswagen is also sometimes called "V-Dub".
As for the "but-why?!!" part of the question I guess nobody can answer you anything but: "for historical reasons".
