You bring up an interesting point... I'm going to resummarise the
expected behaviour of CF objects in the AU world from the host's
requirements - then perhaps we can make up a list of known exceptions
to these expectations... I'll post the list in the next day

I ran into a problem when testing Digital Performer AU support
recently. The problem was that when DP requests the
kAudioUnitProperty_FactoryPresets property, I'd
get a crash in Crystal.
The problem turned out to be a mistake on my part. The docs
clearly state that the host should release the CFArray. I was
continuing to use it after the call.
That got me wondering though. Why isn't this a problem with any
existing hosts? The only answer I can think of is that the
existing hosts don't release it.
Can any host authors confirm whether or not that's the case?
