What happens to older python scripts?

I was looking for an old 2,4x Collada exporter, but the file is no longer available? Why? I thought that Blender had a repository for all Blender related files, or is this not really supported by the Blender administrators when new versions of the software are released? Thanks, Leroy.

The Collada link is dead, so why post an outdated link if the scripts are not available anymore?

Why not just download blender 2.49. When I did just now it comes with the collada exporters
