Ah, I see https://launchpad.net/ubuntu/+source/lxqt-session/1.3.0-0ubuntu2 is the other half of this.
https://launchpadlibrarian.net/688335880/lxqt-session_1.3.0-0ubuntu1_1.3.0-0ubuntu2.diff.gz looks correct to me, **if** the only thing you want xdg-desktop-portal for is the FileChooser - but I would have expected that you would want other portal interfaces to work too.
If you do want other interfaces to work, then "default=lxqt;gtk;" might be more appropriate.
