oh yeah right, it would need much more work/discussion to handle this case.
As mentioned up-thread for publisher/subscriber I think it's fine
(thanks to the replication origin linked to the subscriber) but for
anything else that don't make use of replication origin (or similar
approach to re-start the decoding from the right place after promotion)
I feel like the user experience is not as good.
It may not be worth it to work on it for V1 but maybe something to keep
in mind as improvement for later?
