The general principal of alternating soft and hard layers is still a useful design tool. Even starting from silicon with the microcode emulation of the x86 instruction sets, kernel, syscall interface, building an app and exposing configuration, whether into Tcl, yaml, tool, .properties, json or xml, it’s very likely the consumers of complex software will want to configure its characteristics into a specific use case, but the implementation will be more general. Look at LLM as he ultimate soft layer. Unless your team manages to never write YAML files.
