The only problem is that it wouldn't be quite as useful. Zig, Rust, D, etc offer libraries and methodologies (async/await, for instance) that deprecate traditional raw socket programming. Instead, you would use something like tokio in Rust to do the same thing.

You certainly can program raw sockets, the techniques are almost orthogonal to the beej guide. It's the same API and Structs (using FFI) and you would change some glue logic to make it more rust idiomatic. It would just be less useful in those languages, generally.
