We need to expand the concept of "builders". Is the only builder the person who owns the repo, or does it include, in a wider sense, the people helping that person work more efficiently and effectively? Can we define project teams?
Or are we destined to stay every-dev-for-himself? I mean, as nice as it is to be a dev, being the Product Owner and Senior Dev of a project team is probably even nicer. Just saying. Think about where you want your project to be next year or in 5 years. Will you get there alone?
