When you move away from point and shoots, there are practical reasons:

  • the front of a small camera needs to be strong and rigid to support removeable lenses, especially when you start attaching APS-C lenses onto a mirrorless. It also needs to maintain a rigid "sensor box" to ensure accurate registration of the image on the sensor

No, modern plastics can be just as or more rigid than metal and plastic bodied cameras have metal frames and mounts to support lenses

Have you ever disassembled a Nikon V1? I have. There is no practical advantage for the complexity of a metal cage for the lens mount inside a plastic outer shell like a traditional dSLR for a compact mirrorless camera. The entire front of the V1 is a rigid casting on which lens and tripod mounts are bolted.

  • metal is a good heat sink. With small camera pushing so much RAW data and HD video processing, it is not inconceivable that they would overheat if metal was not used to conduct the temps away.

Metal is a better heat conductor but I have never read anywhere that plastic cameras over heat more than metal ones.

There are lots of reports of cameras overheating with extended video use. Is it not conceivable that of those that are plastic and overheating might benefit from more efficient cooling through the use of more metal?
