I generally agree, but

1. People who haven’t used a package before likely aren’t interested in release candidates.
2. Axum is one of the few pretty well-known Rust libraries. I’m willing to give that a pass on describing what it is for an RC, much like I’d do the same for FastAPI in a Python community. (But a little default blurb about what they are would be nice anyway to people who are new to the language and/or ecosystem.)
