I'd consider your script a well published set of guidelines that I could reverse into a script to run against my own node to see what score you would give me. So maybe I'm not looking for a lightning standard so much as a best-practice for operators to publish their general standards/scoring methods. IMHO, the best metrics are ones that can't be gamed without the metric being realized in a positive way so publishing these things is good because it helps to validate that you really do have a good rule set rather than an arbitrary hack of drunk decisions ;)
