I agree with BPF, and that is what I teach whether PPL, CPL, MULTI, IR. I would say it is not whether you are in an airliner or not, I associate the actions with being on the taxiway/runway whatever.
The statement regarding nav lights that I use is 'consider use of nav lights' so that they are not forgotton.
If you ignore these standards then you get the idiot students when they are on their own or often with instructors, particularly at C******ld, shining their landing lights at you from the hold when you are on final at night ahead of a long line of flashing strobes. just what you need if the vis is a bit misty.
