Ok, I agree the desktop helpers can still be useful for kiosks.
Your comment made me curious what the space savings were on the desktop.
- gnome-3-28-1804 is 169MB.
- gtk-common-themes is 65MB.
- When I switched one of my snaps to the extension, its size fell by 92MB.
So you’d need about three snaps before gnome-3-28 saves you space. I’m guessing this will be difficult on a kiosk. On my desktop, I have 12 snaps using gnome-3-28, so it makes sense there.
This doesn’t seem to be the case for gnome-3-34, however. Only 2 snaps use it and its size is 267MB.
