Hoi,
We have found that duplicate items are created for publications. and so far
the only reason identified is that the lagtime before new data becomes
available is so bad. The notion that there is no practical impact is
therefore wrong.
When WDQS results are considered only for use outside Wikidata fine.
However as WDQS is used for the development of new and improved data you
basically indicate / accept failure by changing / accepting the status quo.
Thanks,
Gerard
