> Basically, Mercurial is migrating away from Python as its primary and core programming language. You don't say Git is written in Python even if Git were to have a few Python code (I actually don't know, never read Git code), would you? Not necessarily. It would show that you can prototype an application in Python and once you have a stable product you would have a migration part to Rust for optimization. That might be even a bit more convincing than the prospect of starting a new project in a non-GC lang.
