What is the point of these questions? If you have a concrete, practical
proposal to make, please do so. Otherwise, you have already got the
answer from the people who are actually working on replication and
understand it far beyond abstract considerations. If you think there is
a good reason to do replication directly in the backend code rather than
as an addon, possibly using an agreed API, then you need to provide hard
evidence, not mere assertion or conjecture.
