The interwiki table for each wiki is necessary for proper processing of interwiki links. We should include it with the public download dumps; right now this is not included, so refreshLinks will insert a lot of bogus brokenlinks entries and default rendering will be wrong.
I would like to propose (and am willing to code) an addition to the Special:Export feature to deal with this for those who get their content that way. It would require the addition of interwiki to the siteinfo part of the xml schema, and some simple additions to the PHP. At the same time I'd add an option for not exporting the namespaces info, as that data doesn't imho need to be downloaded with every article! If there is a willingness to change the XML schema, I'll add this to my todo list.
We do now include the interwiki table in public dumps. (Integrating in the XML dumps would be a separate issue.)
