At least in my case I don't need / don't want any kind of app store in my system (but I understand this is not for everyone; less technical users may not be inclined to installing .deb packages using command line).
And I still follow this thread [2], hoping one day they will clean up the $HOME/snap directory and fix the performance so gnome-calculator doesn't take several seconds to load, but I'm keeping my hopes low.
