This is great, thanks for putting this together! A related question: are we as a community targeting java to be the canonical/target IO language if an IO does not currently exist? If that is not the case, then I would imagine we are hoping that we might eventually also wind up with good examples for implementing IOs in other languages as well [ not suggesting that you/John address that, but that we add GH Issues as that might be worthwhile to hope others take on ]?
