[RFC 3127 said](https://rust-lang.github.io/rfcs/3127-trim-paths.html#changing-handling-of-sysroot-path-in-rustc)
> We want to change this behaviour such that, when `rust-src` source files can be discovered, the virtual path is discarded and therefore the local path will be embedded, unless there is a `--remap-path-prefix` that causes this local path to be remapped in the usual way.
[#129687](https://github.com/rust-lang/rust/pull/129687) implements this behaviour, when `rust-src` is present at compile time, `rustc` replaces `/rustc/$hash` with a real path into the local `rust-src` component with best effort.
To sanitize this, users must explicitly supply `--remap-path-prefix=<path to rust-src>=foo` or not have the `rust-src` component installed.
- The allow-by-default `missing_docs` lint used to disable itself when invoked through `rustc --test`/`cargo test`, resulting in `#[expect(missing_docs)]` emitting false positives due to the expectation being wrongly unfulfilled. This behavior [has now been removed](https://github.com/rust-lang/rust/pull/130025), which allows `#[expect(missing_docs)]` to be fulfilled in all scenarios, but will also report new `missing_docs` diagnostics for publicly reachable `#[cfg(test)]` items, [integration test](https://doc.rust-lang.org/cargo/reference/cargo-targets.html#integration-tests) crate-level documentation, and publicly reachable items in integration tests.
