If you apply that logic you are basically ruling all cantilevered wheel drivetrains ie WCD illegal (excluding bumper mounts)

This is a fun, valuable learning project rather then something that will be ever used in a competition.

This is a terrible style of drivetrain to use in any season( even in 2015 were it is unnecessary) so I don't believe they are intending for it to be legal.

Emphasis mine. I'm not a robot inspector so my opinion is only my opinion, but I would argue that a spinning wheel or axle is not a "fixed, non-articulated structural element" and therefore not part of the frame perimeter. I think the "excluding bumper mounts" exception you made is important, because the bumper mounts are fixed, non-articulated structural elements and therefore count in the frame perimeter, extending it past the wheels of a WCD. That is why I suggested that if they do choose to use this drivetrain or something similar in competition, they should add an additional superstructure (like bumper mounts) to increase the frame perimeter past the wheels.
