After attempting installing and uninstalling several packages I learned that the -R option used here only removes that exact package.
The problem with this is that it doesn't remove dependencies. While running manjikaze update the command failed for me after an orphan package was deprecated.
See these Packman tips and tricks for further improving managing orphan packages. Would be nice to remove orphan packages, similar to apt autoremove, in the manjikaze update command or have a separate maintenance command to take care of this.
