I would never allow a new dev to come in and ask us to completely move away from a tech stack in a project that we're already underway in.

It's one thing to try something different in a new project if it can legitimately solve problems we've been having in old projects.

But this idea that you can do that and most "reasonable people" are going to get behind you on it is balderdash. Most reasonable people are going to tell you no because there's not a strong reason to.

Much better to just move on if you don't like the tech they're working in.

And this is coming from someone who dislikes CoffeeScript, and always has. I would never suggest an active project rewrite their CS in something else.
