As having

this license is, IMHO, the prime reason Wikidata is growing so fast, and

Well, that would indeed be a huge point in favor of CC0 then. Unfortunately,
I'm not aware of any way to turn that into a measurable analyze, as too many
factors might come coincidentally to this. However, since you are
contributor of many open database, maybe you are aware of some studies on
the subject which can back your opinion.
Generally for open projects, the impact is hard to measure. It's not
as simple as determining the sales.
Overview of reuse and adoption by independent project is for me the
most important measure. For example, for Wikipedia that Google shows
it prominently on the search results, that students around the world
frequently use it as first source to get an overview of a topic.
For Wikidata this is not as established, but I would look at the
collaborations. Other databases that have adopted the Wikidata
Q-number is identifiers, for example, like we did in WikiPathways, and
less domain-specific, by OpenStreetMap, if not mistaken. Those
collaborations are a good indication of success: projects invest time
in adoption of it, and would not do it if they did not expect "return
on investment".
I also note
that public domain (which CCZero formalizes across
jurisdictions) is still the "ideal" license when uploading images to
Wikimedia, suggesting more of Wikimedia actually finds the CCZero idea very
welcome.
I'm not sure what you mean here. If you are talking about things like
pictures that the NASA release, I think it falls in the case exposed above.
If you are speaking of the most used license on Wikimedia by benevolent
contributors, I'm not aware of the statistics on this topic, but would be
interested to have some.
My point was that the impression I get when uploading media is that
the more liberal the license, the happier Wikimedia is about it.
Egon
