Only certain actors (specifically rods, softbodies, and granulars) make use of oriented particles. Ropes, cloth and fluid do not use them.
Most actors only work with particle positions and linear velocities. This cuts a lot on quaternion operations, cross products, inertia tensors and the like, resulting in much simpler (and faster) math.
You can check whether a certain actor uses oriented particles like this:

You can see the differences between ropes and rods, and why orientations are only needed for rods.
