The persistent storage of the policy is not settled but adding the sysfs value that's both read and write is safe enough so this patchset is in the list of features for 5.7. With the new raid1c34 profiles we'll need a better mirror selection to utilize all the copies more effectively. Besides the default PID policy we should have at least one more so it's not just the bare interface without any real use.
