In the near future, there will (probably) be a lot more variants about
what it means to be a master or a replica. There will be logical
replication, where you could be a publisher of something and a consumer
of something else. You could even be a logical consumer but a physical
master. So a global binary facility is probably not very forward
looking and will lead to confusion.
