EXTENDING THE QUESTION:

Assuming arguendo –(That is my “bullet proof” vest) , that a golfer chooses a stroke pattern which starts at TSP location at top and transitions to EP for impact.

What are the available/best transition ALIGNMENTS?
Lay-off the shaft at start down ( Sergio, Hogan)?
Sweeping “D” (Stricker)?
Other- like between #2 and #3 release as shaft passes throug parallel to the PL?

What are the implications and effect of the 3rd dimension off plane/under plane forces of the transition?

and, what are the available COMPENSATIONS for this pattern??

This is a Machine and can/should be analyzed as a machine 1-L and 1-L-21??

A lot, I think, depends on how the Player Aligns the Shaft at Start-Down. Some Align to the Elbow Plane while others remain more Vertical and expect to transition the Shaft to the Elbow Plane at Release.

One solution that all Players who shift to the Elbow Plane can adopt is "Double Wrist Action". Then, the Shaft can remain On-Plane without Right Shoulder alignment support and the Right Forearm can return to the Angle of Approach for Impact.
