But one can (and is definitely expected to in many general cases)
to use layered packages. A lot (but not all) of the functionality of dnf
is also possible with rpm-ostree - increasingly so, for example we're
working on supporting "removing" things from the base tree:
Ah, I see, thanks for the clarification; so, long story short, we
*could* actually test using dnf for install / remove / update of
packages on Workstation-ostree? But is this also something that's
already tested in CentOS CI? If so, probably not worth duplicating it.

We already indeed do these types of things in CentOS CI.
Great, one less thing for me to worry about, then. Well. I suppose
there's one more thing to ask: do you test install from the *installer
image* in CentOS CI? If not, how significant are the chances (do you
think) that a system installed from the installer image might differ in
its behaviour from one deployed via a filesystem image or however you
get to the starting state of the CentOS CI tests?

No. There's lots of stuff that isn't yet in flatpak form. And further,
not everything is a desktop app.
OK, so, to summarize, you expect people to deploy stuff on top of
* Via layered packages (which is basically just 'dnf install foo' so
far as the end user is concerned, right?)
* As Flatpaks, installed via GNOME Software
* As containers
Does that sound about right? Thanks!
