IMO this would mostly be useful if you had an architecture that evolved over time where you started with flat files for configuration and later moved to a centralized configuration system, many of which have concepts of references. Duplicating configuration or tapping into some of the advanced functions in here isn’t super helpful when you’re purely dealing with flat files, but this becomes helpful if you’re combining it with some synced external state because you can use this to “smooth over” differences in data shape.
