The goal of the Rise work is to improve and document crates in the web ecosystem that will benefit all web frameworks in Rust. For sure this will mean working closely with the tower, tower-web, and warp projects (and others!) to help find opportunities for using shared components, and otherwise to help build or integrate pieces that are missing.
Indeed! @mitsuhiko is part of the WG and has been participating in meetings setting the direction for the WG, as well as some chats about what he sees as the main gaps in Rust’s story here.
