we certainly shouldn't 😏 - appsettings.json is just one of the many places the settings you see in the app are munged together from, there is appsettings.{env}.json (e.g appsettings.development.json) environmental variables and if people set up things, azure key vaults and all sorts - so you can't garuntee that changing appsettings.json will actuall put your settings into the app.
