Do I need desktop-autostart?

I have both Gnome and KDE desktops installed. I thought this package was giving me problems so I uninstalled it. The package description says “Bundle to automatically launch the GUI upon boot.” but the GUI starts automatically to the GDM or SDDM greeter anyway, so what am I missing by not having this package?

By the way, I disabled SDDM, as both GDM and SDDM were enabled and active, and I think that was causing me some issues like looping back to GDM after I keyed in my password into it and hitting “Enter.”
