Source: xdg-desktop-portal Version: 1.0.3-1 xdg-desktop-portal's package description says xdg-desktop-portal is designed to be desktop-agnostic, and uses a desktop-environment-specific GUI backend such as xdg-desktop-portal-gtk to provide its functionality.
Should xdg-desktop-portal recommend the virtual package xdg-desktop-portal-backend? xdg-desktop-portal-kde in Testing now provides that virtual package, but xdg-desktop-portal-kde was never backported to Stretch. I see that Debian's Flatpak has this so maybe we should just copy it: Recommends: xdg-desktop-portal-gtk | xdg-desktop-portal-backend By the way, I filed https://bugs.debian.org/915115 to propose that meta-kde install the KDE backend by default.
