Eh? That's not what I meant at all. Actually it's kind of the exact
opposite of what I meant.

What I meant was that your description of the "High Availability first
and foremost" is only one possible use case. Simon in the past
expressed the same single-minded focus on that use case. It's a
perfectly valid use case and I would probably agree if we had to
choose just one it would be the most important.

But we don't have to choose just one. There are other valid use cases
such as load balancing and isolating your large batch queries from
your production systems. I don't want us to throw out all these other
use cases because we only consider high availability as the only use
case we're interested in.
