> If yarn had been approached with more senior developers I think it could have replaced npm entirely. Some very senior developers were involved in it's development including the original author of Babel, someone who has been a core member of and contributor to jQuery, Rails, Rust & Ember, people who have/currently work on Chrome, Node core, etc etc etc. If those people aren't "senior" developers, you're going to have to explain what you mean by that. Also replacing npm means replacing npm as the bundled package management tool that comes with node, and likely replacing the fact that they use the npm registry.
