But there's the weird limitation that procedural macros have to be in a separate crate.

Why is that weird? Procedural macros are compiler plugins. They get compiled for the platform you're building on, not the one you're building for, and so they need to be a separate compilation unit. In Rust, the crate is the compilation unit.

Because you can't just throw together a simple procedural macro to use in a specific project, as you can in other languages.
