This negatively impacts the learning-curve of new engineers and community contributors, makes discussions about configuration changes and features difficult (e.g. #3120 #3211 and #3343) and trickles through to negatively impact user understanding and overall experience (e.g. #3187).
To address these challenges it would be good to add a "Config Architecture" section to the Contributor Guide in the docs explaining in detail how configuration flows from meltano.yml, env vars and discovery.yml during elt and run and the steps required to add new config constructs (such as environments, warehouses and connections) to our config system.
