I think this would be a valid rationale if I were presenting 
Boost.KeyValueStore. But to analogise, you are effectively saying "I 
don't see a use for Boost.Atomic because a spinlocked STL container 
does a lot more for me than Boost.Lockfree containers".

Which may or may not be true. But the point here is that like 
Boost.Atomic, until it's in Boost nobody has any idea what exciting 
things people might build with it. Boost.Atomic on its own merit 
seems to have little use.

Thanks for the appreciation.
