As for practices, whether superlative or not, this cannot be a democratic process because too many developers cannot distinguish their own rotten preferences from rigorous coding practices. Throw this open to vote and you’ll get standards motivated by laziness, not solid code. Like early returns, which many still do.
There needs to be someone with final authority who can say, even against an otherwise unanimous vote that
NO. WE’RE NOT GOING TO DO THAT.
