Summary

currently, we autogenerate stubs for lang and libs features (e.g. https://doc.rust-lang.org/nightly/unstable-book/language-features/explicit-tail-calls.html and https://doc.rust-lang.org/nightly/unstable-book/library-features/windows-process-extensions-force-quotes.html). but we don't do the same for rustc. it would be nice if we did, using -Z help.

this will be non-trivial to implement because it requires bootstrap changes so that rustc is built before unstable-book-gen.
