ZFS can do multiple copies of a file on a single hard drive. It is not adding parity.
ZFSOnLinux is developed outside Linux’ tree for 2 reasons. One, it is easier that way and two, Linus does not want it in the main tree. Consequently, you need to install it in addition to the kernel as if it were entirely userspace software. That does not add anymore difficulty than say, installing Google Chrome. :/
