Description

Summary

The native async-fn-in-trait has been available in the nightly version for some time now. Perhaps it's time to start replacing async_trait with this native feature.

Contributor guide

Research direction
Identify all uses of #[async trait] in the codebase and replace them with native `async fn` in trait syntax, ensuring the project is configured to use a nightly Rust toolchain that supports async fn in trait.
