[Offline-l] How important is ZIM support in Collections?

Hi offline community, how important is ZIM support in Collections (the "Create a book" feature) on Wikimedia sites? We implemented this a while ago to support offline efforts. Since collections are still typically very much limited in size, it's not a very viable option for huge offline exports, more for batches of articles on related topics. Do people currently rely on this functionality for offline deployments? We're re-implementing the rendering pipeline for Collections to ensure long-term maintainability, and our default would be to eliminate initially all formats except for PDF if we don't absolutely have to support them. I'll see if we can get some metrics on current ZIM file usage via the Collection extension, but it'd be nice to get qualitative feedback as well.
