Well, I *am* sure. ;-) Let's look at the various parts of GLU:

   * Generation of mipmaps: Part of core OpenGL 3.1, so it's redundant 
nowadays.

   * Matrix manipulation: Not part of OpenGL itself anymore, should probably 
be in a separate math library, which would then offer *much* more.

   * Tessellation: Should reside in a separate, more flexible tessellation 
library. Has a horrible interface in GLU.

   * Quadrics: Immediate mode and display lists are not part of OpenGL 
anymore, consequently these quadrics are deprecated.

   * NURBS: Basically the same as for tessellation.

In a nutshell: Some parts of GLU are useless/deprecated nowadays, other parts 
should be in separate, much more flexible and nicer libraries. Unless I missed 
something, the last GLU spec (1.3) is from 1998, which is another indication 
for its usefulness. But I won't remove it from my current OpenGL package, 
because in its current state this package represents "old school" OpenGL, 
anyway...
