The primary advantage to using an SCM for maintaining these techniques is that those tools help facilitate the merge between the template and its adopting projects.

Without the ancestry, with a traditional copy/paste approach, a [commit like this](https://github.com/jaraco/skeleton/commit/12eed1326e1bc26ce256e7b3f8cd8d3a5beab2d5) would produce notifications in the upstream project issue for each and every application, but because it's centralized, GitHub provides just the one notification when the change is added to the skeleton.
