Well, to answer your question if removing the one table connecting pages and items will break Wikidata-based tools:

Yes, just about all of them.

Hey folks,

we plan to drop the wb_entity_per_page table sometime soon[0], because
it is just not required (as we will likely always have a programmatic
mapping from entity id to page title) and it does not supported non
-numeric entity ids as it is now. Due to this removing it is a blocker
for the commons metadata.

Is anybody using that for their tools (on tool labs)? If so, please
tell us so that we can give you instructions and a longer grace period
to update your scripts.

Cheers,

Marius
