Currently the operator only allows 1 way replication. Would it be possible to support 2 way replication please ?

We're using the operator to provide  geographical redundancy.

If we had 2 way replication, it would greatly reduce the time taken to fail back to the original primary site (bin log retention permitting) instead of having to recreate the DB on the original site.
