So this is a reason to cripple the API -- because 'typical' application
programmers don't know what they're doing? What about those who *do*?

Whatever the semantic difference between 'applications' and 'system tools'
might be, *both* end up having to interact with the hardware via some sort of
API, so I'm not sure that the distinction is particularly meaningful in this
context.

Right, but I think you're kind of missing the point. We're not talking about
garden variety 'audio player' applications here. The world of audio --
especially professional audio -- is a much larger place. This doesn't make
such applications 'system tools', merely applications that work outside of
the simple assumptions adequate when designing garden-variety 'audio
players'. To hardwire those simple assumptions into the driver system is IMO
a design error, one that imposes serious limits on the usefulness of the
overall system. Effectively, it's dictating policy in a layer that should be
primarily concerned with mechanism.
