As one commenter there mentioned, there's no mention of Rust in the article (except a "More Rust code" bullet point). Rust is literally becoming a meme and a buzzword at this point with people getting excited about something when it mentions being written in Rust without asking questions about code quality, speed etc...
Rust isn't mentioned in the article at all.
For the actual change about Rust in 6.4, see this email chain.
