About the init, I think it would be convenient to have an init for boostrapping framework integrations.

For example, have dynaconf init django convert the core settings into pre-populated schema classes, possibly populated with sane default validators and django's own default values.

This is a good candidate for being a dynaconf plugin/extension, as there might be several 3rth party integrations (or plugins of these frameworks) that can potentially want to implement such integration facilities.
