I agree with Maarten and to add to that. It is a huge misconception that
CC0 makes data unreliable. It is only a legal statement about copyright,
nothing more, nothing less. Statements without proper references and
qualifiers make data unreliable, but Wikidata has a decent mechanism to
capture that needed provenance.

Regarding attribution, commonly it is assumed that you have to respect
it transitively. That is one of the reasons a license that requires BY
sucks so hard for data: unlike with text, the attribution requirements grow
very quickly. It is the same as with modified images and collages: it is
not sufficient to attribute the last author, but all contributors have to
be attributed.
If we want our data to be trustable, then we need traceability. That is
reporting this chain of sources as extensively as possible, whatever the
license require or not as attribution. CC-0 allow to break this
traceability, which make an aweful license to whoever is concerned with
obtaining reliable data.
A license is not the way to achieve this. We have references for that.
This is why I think that whoever wants to be part
of a large federation
of data on the web, should publish under CC0.
As long as one aim at making a federation of untrustable data banks,
that's perfect. ;)
So I see you started forum shopping (trying to get the Wikimedia-l people
in) and making contentious trying to be funny remarks. That's usually a
good indication a thread is going nowhere.
No, Wikidata is not going to change the CC0. You seem to be the only
person wanting that and trying to discredit Wikidata will not help you in
your crusade. I suggest the people who are still interested in this to go
to
https://phabricator.wikimedia.org/T193728 and make useful comments
over there.
