Old builds have bugs they've fixed with more recent patches. Reverting to a previous build would reintroduce those bugs.

Also, the game client and server need to identify as matching versions. Notice that the test server required a seperate install.
Do you really think that they don't have back ups of older versions? The only real issue is making sure older versions are compatible with windows 7/8. Companies, and people in general don't just throw out old stuff. Even more so, anyone that programs can tell you this especially in this kind of field. You think lawyers would get done with a lawsuit and just throw away everything relevant to that case? It's a way of life, almost like writing in a journal or something. There is some valid arguments to why SE shouldn't do this, but I guarantee what you are saying isn't one of them.

Better way to explain it. SE makes older version of FFXI compatible with current operating systems. SE just re-implements everything that wait for it......... already exists.
