Which programming languages are the closest to 'finished'? In other words, which are unlikely to expand core features or syntax such that best practices change. C and Scheme seem to fit this, are there other languages?

Every programming language attempts to expand until it has an effect system.

Neat cargo plugin I haven't seen before: https://crates.io/crates/cargo-expand `cargo expand` will expand macros so you can see the regular Rust code produced. For example, println!(); expands to this (even syntax highlighted!).
