Correct:
https://fedoraproject.org/wiki/QA:Testcase_upgrade_fedup_cli_previous_desktop is the only current upgrade test case. 

We could plausibly extend the range somewhat to cover common package
loadouts (GNOME, KDE, minimal perhaps) and common configuration wrinkles
(non-US keyboard layout, encryption, a couple of different partition
schemes), for _one_ upgrade method. Anything beyond that would be a bit
of a stretch, I think.

Correct.

fedup does not use anaconda in any way. anaconda didn't really do any
'tricks', IIRC, it just ran the upgrade in skip-broken mode. I don't
know if fedup uses skip-broken or not.
