Since then, the patch is failing to apply, waiting on author and the
thread has died 6 weeks or so ago, so I am marking it as RwF in the
CF.


I've rebased the patch and made changes so that the patch supports "streaming in-progress transactions" and handling of logical decoding
messages (transactional and non-transactional).
I see that this patch not only makes sure that empty transactions are not sent but also does call OutputPluginUpdateProgress when an empty
transaction is not sent, as a result the confirmed_flush_lsn is kept moving. I also see no hangs when synchronous_standby is configured.
Do let me know your thoughts on this patch.
