I tried to use the spec as a description of disassembled data sections for a toy disassembler I was writing a while back. So I was using the spec but not the tools. It is great that the spec is YAML because that's quick to get up and running. It was just unfortunate that the expression language is custom string, i.e. not YAML. It may have improved, but at the time the custom language wasn't unambiguously specified either.
