This is just a guess, but it might be because the Noctilux is designed 
for minimal flare, and a filter, by introducing another glass-air 
surface, could compromise some of its flare-proofness. 

If I were lucky enough to own a Noctilux, I wouldn't hesitate to use 
filters for control over the image. However, I wouldn't use the 
traditional UV filter for protection, because I don't use those anyway.
