For the upcoming Automated Substrate crates' Release effort, it'll be easier to detect if a crate is not meant to be published if its Cargo.toml includes a publish = false. This is recommended in https://doc.rust-lang.org/cargo/reference/manifest.html#the-publish-field and also is a common practice for other Rust projects, e.g. https://github.com/awslabs/smithy-rs/blob/b2c989630fe42560264be8fe917f3f1950c8e30f/rust-runtime/aws-smithy-types/fuzz/Cargo.toml#L5.

The absence of those annotations isn't a blocker for the publishing since we can work around it through custom exclusion lists, but it'd be nice to have those annotations directly in the repository.

In case all crates are meant to be published, feel free to close this ticket.
