It looks like they're still actively maintaining a bunch of rust crates, and they're still developing Wim (their blobby Roblox competitor written in rust).
They have pulled back from the rust ecosystem quite a bit though since repi (their former CTO) left shortly after The Finals released. They stopped all their FOSS sponsorships, and there was [this PR](https://github.com/EmbarkStudios/rust-ecosystem/commit/61f0e...) which definitely doesn't inspire confidence.
