It would also be nice to include the gvfs-backends (unless these aren’t needed and we can just stage gvfs on it’s own) in the gnome-platform snaps so that we don’t need to hijack the desktop-launch script - at the moment, I’ve added custom code to desktop-launch that symlinks $SNAP/usr/lib/x86_64-linux-gnu/gio/modules/libgvfsdbus.so in addition to the already present symlinking of $SNAP_DESKTOP_RUNTIME/usr/lib/$ARCH/gio/modules/*.so into the cache location before running gio-querymodules (cache location is $XDG_CACHE_HOME/gio-modules).
