First off: this is NOT about James Yeager/Tactical Response.

I want to start a discussion of the concept of moving off the line of force, commonly called "getting off the x"...

I have some opinions, but I want to hear what you out there think first.

Is this technique always appropriate? Is it oversold by those instructors who teach it? Can it be a detriment? What does "getting off the x" actually mean? How does shooting-on-the-move reconcile with moving off the line of force?
