Here's the point of contention...
The precision of a compulsory is determined by a stationary viewpoint (frame of reference).
In an ideal world, both pilot and judges are stationary (depth-wise)...
If the flier moves, say, 50 ft to the left halfway through a compulsory, then the center of the window changes and the judge's perspective is no longer accurate.
Same if either (not both) moves forward or back a lot, again, the frame of reference gets skewed.
I don't have an answer, although I'm familiar with the philosophy you described.
We gave up on competition a long time back even though team members were closely involved in the preparation of the Stack Constitution and Rule Book as I recall.
The static quarter hemisphere 'situation' is a completely unrealistic environment in practical terms except in extremely unusual circumstances and so provides a questionable backdrop for competitive deliberations... In My Humble Opinion, of course! <grins>
