It's amazing there are already so many years available for download. Especially the larger zips must have been somewhat time-consuming to compile! It would be great if 2008 or pre-2006 packages become available in the near future. It is a really interesting development to see http://dumps.wikimedia.org being interested in not only compiling large current packaged databases of various wikis, but also more historic content. In the past, the Internet Archive was the sole distributor of older (also historic) wiki packages.
