From my limited experience with these WikiData suggestions, I think the majority of the problems are at WikiData, not WikiTree, and they need to be corrected at WikiData, not WikiTree.
I consider this a backhanded/underhanded attempt to get WikiTreers to work at WikiData, a site with which most of us are unfamiliar and probably not interested in using.
These suggestions occur even without WikiData references having been added to the related profiles. These suggestions, in my opinion, should not be on our suggestions report when the profiles haven't been linked in an open fashion.
All linking has been done behind the scenes and without discussion or acceptance by WikiTree membership, at least as far as I know.
We should not be expected to have our volunteered time commandeered in this manner. Most of us did not join WikiData, and many of us likely wouldn't want to.
