Obviously not. GSX, as a proper native P3D product, respects LM recommendations in full, and doesn't install ANYTHING inside the simulator folder.
Instead, like a proper P3D product, it only use the add-on.xml method to add its required folders externally, all relative to the main Addon Manager installation folder, which holds together all FSDT product, so they are not cluttering your simulator main folder, and can be easily updated.
