I tend to think that they're not considered "bread" for two reasons:
- Their form factor is not appropriate for the concept "bread".
- They don't contain perceptible air bubbles.
Really, it's mainly the first one.
Two categories can be, um, vocabularily distinguished for pretty arbitrary reasons. Noodles are just a case of the same thing from a nutritional perspective leaving the prototype for the "bread" concept far enough behind that they're perceived differently.
