I think it's especially about Rust in the Linux kernel. There was a lot of fuss as the "foundation" for writing Rust drivers was merged, but since then there has been cvery few news about it going forward and being used to develop new drivers.
The language itself is obviously still going very strong.
Now that you mention it, there really has been like a year since rust has first been introduced the the kernel officially. I don't know if any parts of it have been written in rust as of now or whether new drivers have been made, but I suppose it's most likely still experimental in a way.
