Maybe we should subst out any use of these templates, and then delete the
templates themselves. We certainly should make it as hard as possible to for
new users *find* these licenses and discourage the uptake of them in
preference to ones more compatible with the goals of Commons.
I just feel uneasy about Commons saying "here's an image: you can use it
under either of these licenses", when one is non-free. If contributors want
to offer non-free licenses they can, but ideally it should not feel like
Commons endorses it - "Contact me for alternative licenses" as opposed to a
NC-license on the image page.
