This is my issue with it as well, but also, why did the PR only target Bible apps? Seemingly in a very lazy way at that. Had they taken time to understand how each app works and its purpose, they would have only flagged apps that contain the Bible itself. I would hope reddit and other apps that actually contain graphic NSFW content are next?
The only merge request you've seen targets bible apps. How do you know this isn't one part of a larger effort to correctly mark apps? Maybe they've tackled other categories previously, or had intended to tackle other categories going forward. The fact that bible apps is included in one wave of markings doesn't mean only bible apps are affected.
