This is one of the reasons for why I prefer C over Rust for reference implementations. I look at the code and I understand it much better than the Rust version.
I think I agree with this. C is, if nothing else, very simple to read and understand (generally). For reference code, it seems like a good choice. I think you need a stronger argument to use C over any other language for something that is meant to be bullet proof or run in production though.
