Well the replication changelog can not be used for anything else but the
multimaster replication plugin. If a customer increased the replication
purge delay you could potentially run into issues, but again this only
comes into play when a replica is down for a very long time. I'm not
sure if IPA even provides the option to adjust the replication purge
delay, but that doesn't mean a customer can not adjust these settings on
their own.
