I disagree with your first point, at least from a personal perspective. I find Rust more expressive than Go, and slightly more productive.
You're right about maturity though. Hopefully the Rust library ecosystem continues to make strides.

To tie it back to the article a bit, Rust also seems like a relatively natural choice for a team considering switching from Haskell if their reason for switching is performance. The niche Rust fills for me personally is that it has a very robust type system (putting it in a similar camp as Haskell) with an explicit focus on fast, performant code (which Haskell does not have).
