Dont' we already have the beginnings of such support with Canonical's support of ZFS in the Ubuntu Linux kernel? I'm writing this reply on a system running ZFS as the rootfs.

    % findmnt /
    TARGET SOURCE             FSTYPE OPTIONS
    /      rpool/ROOT/default zfs    rw,relatime,xattr,noacl

Regarding Linux kernel on Windows 10, if you're referring to The Linux subsystem, there's no Linux kernel there, it's a Windows subsystem implementing the Linux system calls directly. Unless you're referring to full Hyper-V virtualisation, where you can run FreeBSD just as you can run Linux.
