That requirement falls out from the handling of disconnected standbys. If a

exist. Otherwise it can't know if all the standbys are connected or not.
Thanks. I understood why the registration is required.
I don't. There is a simpler design that does not require registration.
Please explain why we need registration, with an explanation that does
not presume it as a requirement.
Please explain how you would implement "don't acknowledge commits until
they're replicated to all standbys" without standby registration.
