That depends on if we consider this to be part of sequence handling or
truncate statement replication handling. It's true that if we had
sequence replication, the restart would get propagated that way anyway.
OTOH, if we'll want to add option in the future to propagate cascade (to
any additional tables on downstream), it may need to reset sequences
which are not even present upstream and as such would not be handled by
sequence replication.
