I have proposed this on the official Rust users forum too, where votes are in favor, and the decision by mods is pending.
Edit: Discourse thread structure doesn't fit this purpose, and because it's more natural to use a platform where more developers are found, I have created a GitHub org and invite everyone interested to comment here.
I have seen companies post jobs in git repositories (e.g. GitHub). So maybe as something by and for developers, and a way to filter out recruiter spam, as a community we could maintain a repo with one GitHub issue per Rust release, inspired by Awesome Rust lists.
