if you have DS installed and unlocked or a backup of of 4.8. your content will always be usable in DS.

You will NOT be able to simply roll-back your DS installation after the encryption goes live. If your post-encryption copy of DS locks you out, any encrypted content will NOT function in an earlier version, because the ability to decrypt that content does not exist in earlier versions.
