These files are marked %ghost to prevents them from being removed *if they existed and were modified* prior to commit 4c7acde (Do not remove modified config files, 2023-12-13)¹ on the f40 branch of the systemd package.
And perhaps I should have also noted the earlier commit which moved them from /etc to /usr/lib, 29eb355 (Move config files to /usr/lib/systemd, 2023-12-08)¹.
