I used to teach it because it was testable in an oral exam for private, commercial, and CFI tickets. In reality, it may play a minor role in yaw moments, with gyroscopic procession, P-factor, and reactive force causing most of the left turn tendencies. In fact, the FAA texts refer to Spiraling Slipstream as a theory, so I framed it such and moved on.
