I'm in favor of this but it needs a migration guide :)

I added the migration guide. Do I have to do something for the Ci fails or is it normal ? I don't have any error when I try locally

CI appears to be failing all over today: I think we have a Github problem. For now, just resolve merge conflicts and we'll get this in when we can :)

Ah, the migration guide should be in the release-content/migration-guides folder, not the PR description now! That makes it easier for us to automate.

The generated examples/README.md is out of sync with the example metadata in Cargo.toml or the example readme template. Please run cargo run -p build-templated-pages -- update examples to update it, and commit the file change.
