First Google result points to "unpublished" book, which is identical to published one

To Reproduce Steps to reproduce the behavior:

1. Google "rust wasm"
2. Click on the first result — https://rustwasm.github.io/book/
3. The page says in red "This is unpublished documentation of working with Rust and WebAssembly, the published documentation is available on the main Rust and WebAssembly documentation site . Features documented here may not be available in released versions of tooling for Rust and WebAssembly. "
4. Clicking the " on the main Rust and WebAssembly documentation site " link takes to a seemingly identical page, on the same site, just without this warning.

Expected behavior I would like only relevant and accurate content to be hosted and promoted, not a mix of near-duplicate dead pages competing with real ones in search results.

Additional context If a page is outdated, just delete it. Use robots.txt to remove dead URLs from search engines.

Ping. This is still broken.

It seems that this was done on purpose: https://github.com/rustwasm/book/commit/48d360e62cb57fb8c68c27653b96a72724745d0b

As you said, both pages appear to be identical. It's a simple thing to remove I just don't know if it's still serving a purpose.

I'm not sure what's the intention here. It's confusing to publish something online, in search engines, and then call it unpublished.

If one of these copies is preferable, then the pages should have <link rel=canonical> pointing to the right one, or exclude less desirable copy from search engines using robots.txt or <meta name=robots content=noindex>.
