No ductwork??

Is it a great idea? no.

Would I call it out? yes

Whenever I see something out of the ordinary I call it out and express my concerns apart from any code.

Exactly…

It is not irrelevant by any means. Read the NEC.

This wiring method is simply not permitted in environmental air passages.

If the wiring was in pipe or using approved materials you could have this type of plenum.

Is it a great idea? no.

This can be a very efficient system if done properly. The partions between conditioned space and unconditioned space MUST be insulated and sealed well. The floor gets warm as would a floor woth hydronic heating coils installed in it. It is essential that the btu requirement for each room be closely calculated and the floor heat output and register output co-ordinated. The space is actually the “supply air plenum”
