Thanks for the correction! I conflated what (I believe) some rust teams use as the thing that every thing in official rust uses. I think Rust uses both Discord and Zulip[0].
They're on the bigger side, due to a combination of defaulting to static linking, some optimizations not having been possible (ThinLTO comes to mind), lots of debug strings and metadata, as well as the use of jemalloc[1][2].
I don't think it's fair to say that Rust is entirely academic. It has a lot of production users including some very large names: https://www.rust-lang.org/production/users
In the replies, they said they are planning a blog post to talk about the tech in-depth. Looking forward to that! Apparently they’re also deploying Rust + Elixir via a NIF.
