These special versions of Safari use the original Web Kit framework that came with them, bundled inside the application. They will mimic original Safari rendering and javascript behaviours. HTTP requests and cookies however are still handled by the system and may not work exactly the same.
Looks like the only big caveat is needing a Panther and a Tiger OS to run the Safari versions dependent on those versions of OS X. Includes 1.0, 1.2, 1.2.3, 1.3, 1.3.1, 1.3.2, 2.0, 2.0.2, and 2.0.3
