A few notes from our perspective:

• Bundling should include (a selection of) wiki pages from all namespaces and images/files, but perhaps also other resources, e.g. logo.
• One should be able to manually (from a special page) make a selection and start the bundling, like now with Special:Export
• It should also be possible to select&bundle automatically, i.e. from a script or command line
• There should also be an "unbundling" option, to deploy bundled content, again both manually from a special page and automatically from a script or command line
• The automatic process is useful for transferring content and resources from an editor instance to a public instance of a wiki, where the public instance serves an approved subset of the pages in the editor instance
• The manual process is useful for deployment of content and resources in a dev/test/staging/production environment. In many situations, security directives prohibit automatic deployment in a production environment.
