I think all of those artifacts and imperfections which are obvious in spotlighted isolation just don't have much of an effect in the context of actual music.
I've worked with libraries that have far more glaring inconsistencies than what's been demonstrated from this one, and still managed to make music with them which is just fine (sonically; can't speak for my abilities as a composer).
If anything, slightly unpolished samples are what add humanity to our world of musical illusion, provided that they aren't totally compromised in playability, or obviously repeated in round robins. I have no reason to feel that either is the case here, unless you insist on using regular longs as detachés, I'll concede.
Although, I bet that could be done fairly convincingly with a breath controller.
I think SStS, and the series as a whole, will ultimately fare very well, and I'm following it quite closely....
