Thank you for this :)

I think this is great & we can merge as-is, but one thing I wonder is whether the "Manage the RPC" comment makes it into the CLI. Have you checked that by running cargo run -- --help? I think the comment may end up "unused" due to the #[clap(flatten)].

Anyhow, still good to have this. Next up some help in the submodules (authors/blobs/start/tags etc.) would be amazing! :)

No, it doesn't show up in the CLI, directly picks up the subcommands. I guess that's why it wasn't documented. It'd be nice if it could have the "Manage the RPC: " in front of every subcommand, but I cannot find it

Yes, I have done the other submodules too! I wanted some feedback in case I missed something, so I fix it before opening the other PRs.

Thanks!
