From what I've read,
sudo pacman -Rs + package(s) should only remove the package and any exclusive dependencies, i.e. not used/shared by other packages.
When I used the command, it warned me that another package depended on another package and removed it anyway. I had made a note of the package before proceeding. so, I tried with pamac.
I have the option to remove unrequired dependencies on, but that issued the same warning and went ahead and removed the package. I thought that it is supposed to leave shared dependencies alone.
