Hi Gregor,
the main reply to your concerns is that we are not ruling out that
further things will be done once the basic system is in place. Most of
the doors that you mention will remain open. The approach in Wikidata is
to deliver results early and frequently to the community. Therefore, we
have deliberately limited our scope in various ways, focussing on our
core tasks. This will already cover a huge amount of hitherto unmanaged
data, and it already bears many challenges that need to be addressed
first. But we certainly hope that this is only the starting point for
Wikidata.
Cheers,
Markus

This is a valid point. It is intended to address this as follows:
* Wikidata items (our "content pages") will be in *exact* correspondence to
(zero or more) Wikipedia articles in different languages.
* Differences in scope will lead to different Wikidata items.
* Relationships such as "broader" or "narrower" can be expressed as
relations between these items, if desired.
This is a technically valid solution. Socially, I fear it would lead
to endless uncertainty which mechanism to use. Few abstract entities
will have exactly the same delimitation/width, but where should one
switch from one method of linking (one wikidata page with several more
less closely matching wikipedia pages) to the other (several wikidata
pages, one for each wikipedia page in each language)?
Also, importing data will be a nightmare, because the concepts used in
imported data will have to be compared with all wikipedias. One
Wikipedia-language-version has the post-WWII extent of Russia as well
as the current and another Wikipedia-language-version has them
separated. It may not have mattered before and only one Wikidata page
links to both language-versions. However at some point historical data
are imported and suddently Wikidata needs to be reorganized to have
two pages. ... Just thinking loud - this may be unavoidable perhaps...
However, my gut feeling is that if you plan to avoid relations between
Wikidata and Wikipedia, it might be a more comprehensible model to
then always using only one method, i.e. have a 0 to 1 or 1 to 1
relation between Wikidata page and Wikipedia page only, and express
everything else in Wikidata to Wikidata page relations. These
relations are then easily traceable and updateable, just as the
broadness or narrowness of a page in a given Wikipedia develops over
time.
In general, Wikidata will not be able to replace all interwiki links: it
will remain possible to define additional links in each Wikipedia to cover
cases where the relationship between articles is not exact.
This worries me. It means that there will be forever conflicting
systems of editing interwiki links. If everything can be achieved with
Wikipedia, but only a subset with Wikidata, it spells social adoption
danger.
