In go, `go mod init` and `go get go@latest` (both recommended commands), both set a 'go <latest-version>' stanzas. In go, you _must_ set a minimum required version.

If you type 'cargo init', you will get 'edition = "2024"', but no 'rust-version'.

The situation is different because rust does not require a 'rust-version' in Cargo.toml, and in practice most crates do not have one, while in go it is required you specify a minimum version, there's no automation to set it to the true minimum, and most projects update it incorrectly in practice (because the go cli updates it incorrectly for you).
