We discussed this case upthread. We ideally can handle it via
conflict/resolution strategy or simply avoid updating the sequences
that are synced from the publisher. If we do later it would be tricky
because we need to maintain a persistent state and then after
failover, that state should be cleared. We discussed to have it
documented that users should use such sequences only during upgrade or
for failover cases, allowing to update it actively on multiple nodes
can lead to inconsistency.
