Highly recommended for tweakers. Or: if you know you'll only be using either the GUI or the CLI version you could install only the ony you prefer, and then you don't need this meta-package. Note: This is for tweaking Nemo, Cinnamon, and Cinnamon specific packages *only*! If you have installed extra apps yourself, there's a good chance many of them are developed for gnome (MATE) and to tweak those you'll need to also have the gconf-editor package.
