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.
