Hoi,
Apparantly at Commons they have standardised themselves to only support
Wikipedia.
At Wikidata we have people who are notable according to our standards. We
are actively asking them for images to illustrate our information. The best
suggestion we get is: do not ask for images because they are deleted at
Commons.
When this is what awaits us when we standardise on one label Wikipedia, it
is obvious that this is the worst scenario for the "other" projects. The
projects who operate to different standards who have notability criteria
different from English Wikipedia.
Thanks,
GerardM
