Day to day rust users shouldn't care too much about pin_project since the big use case for pin is handrolled futures and executors. Most folks just use adaptors from the futures crate and one of a handful of executors in the ecosystem. I've never actually heard of that other crate. It looks like most of its downloads come from its direct/indirect dependents like glium. I'd say if you're writing self referential data structures you're not writing idiomatic Rust.
