I think there should be uninstall instructions for the CDN added, because I tried to find out how to uninstall it prior to migrating to a new server, and there was no info about it and the rep I spoke with said it should be fine to leave it on. However, when I migrated, my site broke and images didn't display properly, so I think we need uninstall instructions for uninstalling our CDNs before we decided to mirgrate to new servers. They tell us how to get the CDN on, but they never tell us how to uninstall it, and this leads to sites breaking which leads to support problems.
