@S1m I have my doubts towards the former (that would mean rolling back their implementation, at least in parts, and using the suggested patches instead, which they rejected. The argument was that f-droid.org itself does not need key rotation, IIRC.). And as long as we still use fdroidserver, the only way we can notify is via the inlined per-release changelogs (aka "Fastlane changelogs"), which is what we do.
