Actually, you're correct, the -x/--exclude settings are not currently
propagated to the upgrade. I filed an issue on github to track that:

  https://github.com/rpm-software-management/dnf-plugin-system-upgrade/
issues/29

I *can* add that to the State object that dnf system-upgrade uses to
pass the --best/--allowerasing/etc. settings between the download and
the upgrade, but I think the best long-term solution is for DNF to
provide some .save()/.load() method(s) that will correctly save *all*
the relevant configuration and transaction bits, rather than trying to
figure all of this out on my own in an external plugin.
