Maybe the best we can do is to document in README.Debian, that users of an alternative NTP client, have to disable systemd-timesyncd manually. The Condition is only a hack and I'd rather not add it back. It's not a proper solution either, as it only checks for the existince of the binaries, not if the alternative NTP services are actually running.
