If you don't want workspace enabled and are on version 8, unused_deps did not work due to the lack of workspace support. You could either fix this by adding it to your project's bazelrc however we conditionally enable it here depending on the version of bazel being executed. This does have the side-effect that it seems to cause a rebuild due to the arguments of the CLI changing.

There was a problem hiding this comment.
We could also use this to conditionally, create a MODULE.bazel file and then use override_module instead of repository; I guess both approaches could work and that would probably needed eventually for Bazel 9+ when WORKSPACE is gone.
