Hey @Mueschel, I don't know the basis for your biased comments.
But here is the thing I mapped these libraries with a team through a project title "Ugandan Libraries Geo Quest" under Wikimedia community User group Uganda GLAM project to create an interactive webmap which I created, and I wanted to share the same data that I had updated and added about the different Libraries on Wikidata and Wikipedia. So, I don't understand why saying there even points in water that non is close to the addr:, are sure about that?, there Mukono district which has places in L. Victoria, are you aware of that?

I used Umaps to create the webmap: https://umap.openstreetmap.fr/en/map/community-public-libraries-in-uganda-ugandan-libra_1147102#7/-2.875/32.662

Here is my conclusion, if you feel the changeset needs to be reverted please go a head!
