There are two issues: firstly, the definition of modification and secondly, the utility of removing the rotating portion of the CIM.
Modification isn't straightforwardly defined, particularly because it's difficult to account for the cases where something is disassembled, and then reassembled in a functionally-identical way. When the assembly was apart, it was clearly modified, but it is arguable whether reassembly restores it to an unmodified state, leaves it in a functionally-identical modified state that negates the illegal modification, or leaves it in a functionally-identical illegally-modified state.
As for removing the CIM shaft, although it's straightforward to open the motor up and detach the rotating parts from the fixed ones, I don't recall it being practical to remove the CIM shaft from the armature. As a result, overheating the varnish is still a concern (but overheating the magnets would not be). But you're correct that this would nevertheless simplify the process significantly.
