Have a look at Arminius, introduced at the Matrix conference in Malmö mentioned in the article: https://gitlab.com/bundesmessenger/backend/neo/arminius/arminius
The German military is building a new open source Matrix server implementation in Rust, intended specifically for enterprise-level use cases (authentication, cloud-native, scalability).
This will be very interesting to watch, and will be an important step to reducing the ecosystems overall reliance on Element.

The people working on it also built the Matrix Rust SDK as far as I know and have been doing that kind of work in Rust since before AI coding was a thing.
