Leadership comes from action and to avoid “who are you to decide” you need structure.
The only structure we have currently are RFCs.
The debate linked above is a good example of unclear guidelines as different reviewers are trying to ask for different kind of standards in our community.
There’s a lack of “what is the minimal decency we expect from communication” and a lack of “what is the minimal accepted set of rules to get your contribution merged”.
How do we solve that? Someone has to do the hard work.
