Sure, I don't deny that HS by itself would have significant use cases.
But what those zillions of users want is easy-to-set-up replication
(think mysql). Without an integrated and fairly high-performance log
shipping capability, they are not going to find HS very compelling.
Claiming otherwise is just wishful thinking.

My own feeling about it is that once we have both HS and log shipping
integrated and reasonably well polished, we'd have something that
deserved the fabled 9.0 version number. But that's probably a year
away, and we are not doing anyone a favor by not putting out 8.4
in the meantime.
