makes sense if you have a site or app factory doing the same pattern over and over (I guess its obviously a comment)
in other ecosystems such as Drupal for instance, they have an Installation Profile and a Distribution concept and platforms like Acquia and Aegir can manage these site/app factories
platforms like Pantheon allow Drupal distributions to have a git upstream, so you can keep a core distro updated from an upstream proprietary or open source community distribution PLUS maintain a custom code and config
so, THANKS
