It was actually a mistake. They were removed years ago specifically for the fdroid builds, but were reintroduced at some point on accident. Annoying mistake for sure
If the app is hosted at its own F-Droid repository, devs can add whatever they want. I wouldn't be surprised if that build is the exact same one as the Play Store one.
Nevertheless, good step for users! I wonder how devs will get crash reports and such stuff now, though...
How? For 2023.10.0 appmanager's scanner does not show any of those, and it is usually very through (even right now it has identified 54 programming libraries)
