IANAL but it's important to understand what is and isn't enforceable regarding a trademark. I can write about Debian, Firefox and Rust without an explicit disclaimer that I'm not endorsed by their corresponding foundations if it's obvious in context. I can also write about Coca-Cola, Nintendo and Oracle in a similar manner. It doesn't matter what any of the trademark policies say.

I wouldn't worry about writing on rust, the language. It certainly sucks that the language, the compiler and the foundation share the same name. But it probably sucks for the foundation as well regarding enforcement.

I don't get why people like to put the name "rust" in crate names, unless they write tools that work with the language (linters, auto-formatters), it just feels redundant.
