I'm pretty sure that I've read an aphorism along the lines that every configuration over time develops into an ad hoc programming language (similar to Greenspun's 10th rule so maybe I am just misremembering https://en.wikipedia.org/wiki/Greenspun%27s_tenth_rule)
At any rate the closest I could find to this saying was this HN post https://news.ycombinator.com/item?id=8092967 "Configuration files suck. Just use a programming language"
>but you could use the tool’s url as the key so it’s unique.
reminds me of XML namespaces.
