Don't look fundamentally different? May I'm missing something but I have not seen a single tutorial or article about something Debian or Firefox that starts that with the disclaimer "This is not affiliated with the official Debian etc" Like the R** Foundation is asking to.
Let's not even mention the unreasonables of not being able to name package writen in R** as package-rust.=, somethng that no other programing language forbids as far as I'm aware of.
Go ahead and write a tutorial about Rust without a disclaimer. This is totally non-enforceable, trademarks can't limit talking about the thing. As long as it's clear that you are not representing them, it's fine, even without a disclaimer as described in their policy.
IANAL and this is not legal advise, but I wouldn't sweat about it. This same thing applies to any other trademark too, be it Debian, Firefox, Nintendo or Coca-Cola.
