In order to fit the extension into the rust release process, we'll need to publish this extension onto crates.io. Ideally this would just get pulled in with the submodule, but some people don't like that. It's a bit unfortunate, since it will make it a bit more difficult to make updates (requiring publishing mdbook-spec and then separately updating the version in rust-lang/reference).
I'll follow up with automation for publishing new versions via GitHub Actions.
