The components are supposed to be available in the feed so that the skin can be installed properly. Otherwise, the image may malfunction, or the installation won’t complete and will ask for the supporting package needed for the skin. This way, the image gets corrupted, and you won’t realize the problem until it’s too late. The only way to fix it then is by doing a clean, fresh installation.
In addition, the extra component is not available online — I searched for it but couldn’t find any trace of it.
