> Throughout the code base we do things like `config:get("couch_httpd_auth", "authentication_db", "_users")` which exposes internal details to other applications that don't need to be aware of the particulars. This duplicates code unnecessarily and causes problematic typos to go unnoticed like in COUCHDB-2628.
> One possible approach that I'm a fan of is to go into the application responsible for relevant config value, and add a function to hide the details. For instance, this is done in `cassim_metadata_cache:metadata_db`: https://github.com/apache/couchdb-cassim/blob/windsor-merge/src/cassim_metadata_cache.erl#L58-L59
