There's no strict need to use pacman -Rdd here, that part is not that relevant.
True, but what is the usecase for the sudo-ra package then?
From a security perspective I'd recommend removing sudo when switching
to sudo-rs. Otherwise the system still contains potential security
vulnerabilities shipped with the sudo package, in addition to the ones
shipped by the sudo-rs package.
The point is that this package doesn't bring much. A simple /usr/local/bin/sudo
symlink pointing to /usr/bin/sudo-rs would basically achieve the same (then
removing the sudo package from the system is users' choice).
We require package submitted the AUR to be (somewhat) useful [1]. This one is
arguably not (given the same result can basically be achieved with a simple
symlink).
This is not true. Even if the user could remove the package in a
recommended way (not -Rdd), this renders the sudo-rs package useless,
because it misses at least a PAM configuration.
