LXC is a jail and qemu is an extra layer of emulation. Why pay that extra cost? Just because it serves a wsl image isn't really an answer. How is that worth the extra layer?
EDIT to not be a dick about it: I think the key detail here is the difference in isolation between containers and VMs, and where emulation comes in.
