That tangle is not strain relief. Those wires are buried in injection-molded plastic. Pull on them and those loops will not stretch as they are in solid plastic. What they will do is potentially result in unwanted cross-talk between wires as loops start acting as antennas.
Thank you. If I may, is injection molded plastic not solid plastic? To many potential voids?
It is solid, which is why the wires cannot move. Molding the thing as one unit overtop the electronics is cheaper than making many parts to clamp over them as a box. A solid block is also generally better for strength and thermal.
