From the headline I thought they were making a single incremental change (Nix) but the article sounds like they’re doing an entire rewrite under a new project name:

> Since we transitioned away from Nix, we also transitioned away from the name Nixpacks in favor of Railpack. We also changed the codebase from Rust to Go because of the Buildkit libraries.

Suddenly the move away from Nix seems less like an incremental change and more like one part of a complete overhaul of the entire project. Did they have a team changeover or something? Or did they just want to start over from scratch and rewrite the whole project?

It also seems strange to switch to an entirely different programming language for a single library. I haven’t found library FFI to be a huge obstacle in Rust.
