  I think that the reason is mostly historical.
  For some primitives certain transformations are handled in a special way.
For example, if you translate a sphere, no transformation matrix is generated
for it, but its center is simply changed accordingly. This is a kind of
simple optimization. Of course this means that referencing is not possible
with this feature.

  I don't remember if anyone has actually measured if it really affects the
speed of the rendering that much, specially with usual scenes (instead of
artificial ones constructed just to measure this).
