I'm in the same boat with BABLR, which is designed as the successor to Babel (and named with a nod to ANTLR). I think this is just part of the benefit of free software and OSS, that someone can pick up the work and start trying to innovate without being given any kind of explicit permission. If you understand the mission and are willing and able, you can pick up the flag and start trying to run with it. You might not instantly become the recognized standard bearer for the cause, but keep pushing the flag forward people will take notice (as we are doing here).
