This seems like another instance of the above pattern, where "Rust community" is simultaneously:
(1) The set of people who talk about Rust online in major forums, such as Twitter and Reddit, and
(2) The set of people who post on the moderated low-traffic official forum.
I don't think most people, when someone says "Rust community should ...", would consider that to be scoped to people posting on rust-lang.org.
Consider that according to https://users.rust-lang.org/u there are 22,000 registered users on the rust-lang.org forums. There are currently 191,000 people subscribed to /r/rust, and since it's Reddit there's no need to be subscribed to post or comment. The number of people talking about Rust on Twitter is less practical to count, but probably at least the same order of magnitude.
