Since docker shares host kernel, why most docker images contain the kernel stuff?

As someone answered the relationship between docker image and host: https://stackoverflow.com/a/18859958/1516361

I'm wondering why the image of docker still contains kernel stuff (kernel image, .dtb files, etc.)? Except making it possible to run on non-Linux host OS (uses virtualbox instead, so it needs a bootable kernel), so what if the host kernel is much different with the image attempts to simulate?
