It might not be such a bad idea. If the main goal is to develop a specification or standard then it makes sense to have several implementations. The implementations can be used to flesh out and improve the specification. Also, from their website: Why rewrite it in Scala? The Scala implementation is not competing with the OCaml implementation, we do plan to maintain both in the future. Having several implementations of the core forced us to really think the formats through, and will allow others to write tools in the languages the like best, for their favorite platform (try to get and compile OCaml Pijul on Windows!).
