snap-store consumes 200MiB memory and 50MiB+ disk I/O (for half a day) in the background, and snap consumes lots of disk space. I haven't used them manually but it seems that they provided gnome and gtk:

Will removing snapd (from apt) and snap-store (probably from snap) make the life more difficult, e.g. having to reinstall the whole gtk & gnome?
