The http crate seems to be used by many popular frameworks: https://crates.io/crates/http/reverse_dependencies

It's used by at least Actix-web, Tide, Hyper, and Warp. Generally, this crate's types aree re-exported from the main framework so you can avoid adding extra dependencies to your application, but AFAIK the compiler can "see through" the type alias to see that the types are the same.

I think the older generations of web frameworks (like Iron, Nickel, and Gotham) might not have leveraaged the http crate, so your point still stands.

Hyper and Warp both use the http crate because they were written by the same person who wrote the http crate. All the other frameworks, including actix-web, tide, and rocket only use it for repetitive types (headers, statuscode) but have their own request, response, etc. types
