Versioning crates in workspaces

this package uses tags like crossbeam-utils-0.1.1 to get the source for the crate within the workspace.

Is this rust standard now? I saw some workspaces where every crate has the same version. Are there any workspaces that don't follow this system?

Some workspaces use the same version for every crate. Some workspaces use different versions for different crates.
