Hoi,
How do you compare functionality that is totally broken with "another tool". Or is your tool broken as well?
As to Commons, we once had a Wikidata provided search tool that allowed search in any language. It was "adopted" by general search and is now no longer functional. In essence it provided a service where an eight year old could find pictures in any language. When asked if the functionality could be revived, the answer was "that is not our mission".
What we see is another type of bias. It is the bias that comes with the highest usage. It is not considered why the other functionality is hardly used given that it is abandoned, given that it is broken, given that it is not used by our group. Who in the WMF is the designated champion for projects like Wikibooks, Wiktionary, Commons? Seeks out what we can do and make a bigger impact?
Thanks,
GerardM
