It smells like a variant of inner platform effect. Where in order to save you from programming the the config is super flexible, What is missed is that you are still programming only now you have to do it in some weird context.

At least in this case it is an actual programming language instead of XML or YAML like so many of them.

An alternative slightly more charitable interpretation is this is the engine/gamelogic pattern. But the difference between the two is more subtle than it naively appears depending largely on proper layer segmentation.
