I think you still need to explain what "true" synchronous replication is.
IMHO eager replication is of value only in a very localised sense. It
doesn't help the general case where the location of servers isn't
known or is known to be distributed, since it causes huge performance
drops in those cases.
Given sufficient resources (time, money, skill), it would certainly be
on the list somewhere. But at present its far enough down the list to
not be actively worked on, speaking personally. Please don't read into
that some form of opposition.
