Provide version control support for Team Process artifacts, such as areas/iterations, global lists, and WITs
TFS should support the provide version control support for artifacts of the active team process, such as areas/iterations, global lists, and work item type definitions. There is currently no way to view or roll back changes to these artifacts without using a manual process to export, checkin to a (manually created) version control path, edit the "offline" artifact, checkin changes, and the upload the changes. This should be natively supported, and should be transactional/atomic.

Definitely a good idea. We've tried to do this somewhat for Builds, but you're right there is a lot of integration missing for all things related to the process template. Ideally, we'll build better tools to edit and manage process customizations, and those tools should be integrated into VC to version items properly.
