Meh. Possibly a derivative work under some laws, I don't know.
Though CC-BY-ND, for instance, explicitly allows transfer to different media,
and modifications necessary for such.

Sorry, isn't that the case under discussion? By "user of content" we mean people
including someone else's content in Wikipedia, rather than people using
Wikipedia's content, right? Because the first question in the FAQ is, in fact,
"Can I add to Wikipedia something that I got from somewhere else?"
The FAQ has a whole section on licenses. It even has a specific sub-section on
Creative Commons licenses. There is a general prohibition on that page against
non-commercial licenses, but nothing about non-derivative, not even in the
specific sub-section.

I did in fact look at that page as well, and that is not the relevant section.
That section is about whether you can upload the media. For example it also has
the option "you own the rights to the image" and one for "fair use".
You then go down just a bit further to find what "free license" is acceptable.
Again, it explicitly forbids non-commercial use licenses, but is silent on
non-derivative licenses. You then go to another page for "acceptable image tags"
(WP:TAG). Again, a general prohibition on non-commercial license is stated
(sort-of... e.g. if you go all the way down under generic free licenses), but no
general prohibition on non-deriv. Of course, under the specific creative commons
section, you would not find no-deriv licenses.
So I found it less than clear, even for "creators of content" rather than "users
for content", and rationale is not given in any case.

But if the downstream users are doing something different, then they might not,
and in any case a fair use claim is not a let to make derivative works
(notwithstanding media transfers, which as I say is allowed anyway).
It seems to me that CC-BY-ND, therefore, is intermediate between a copyleft and
fair-use. And we do, as you say, allow fair use, under some circumstances. We
should therefore allow CC-BY-ND under at least the same circumstances, and
probably more. No?
