Boy I was half asleep when I wrote that comment, all I was saying was that since github lets you reference previous versions of files by crafting the URL properly to include a tag/branch/hash, it should be possible to link to previous versions of the documentation straight from the latest version, eliminating the need for someone to clone the repo to access them.
