I use a similar library called Schema at https://pypi.org/project/schema/ I love the expressive nature of it. Just this week I was validating both yaml and json configuration data with it.

One thing missing from this article is to always use a proper external key value store for everything but the stage (dev test prod etc) and the connections to the kv store. Config files on disk and even in environment variables suck for anything but the most trivial platforms.
