This is an interesting commentary on the priorities of the customers
you're selling to, but I don't think you can extrapolate from that too
much. The deployments I normally deal with won't run a system unless
there's a failover backup available, period, and the fact that such a
feature is not integrated into the core yet is a major problem for them.
Read-only slaves is a very nice to have, but by no means a prerequisite
before core replication will be useful to some people. Hardware/machine
resources are only worth a tiny fraction of what the data is in some
environments, and in some of those downtime is really, really expensive.
