I would like to add one point to the discussion: low latency is important for a whole class of other applications besides audio.
For instance, distributed lock managers and buffer coherency managers for things like distributed file systems (eg, gfs), or databases (eg Oracle OPS). These tend to run on heavily loaded systems but still need intersystem/interprocess round trip latencies in the few millisecond range, not the multiple tens of milliseconds currently seen under load. However, unlike audio, they only need good average performance and are not hurt by the occasional worst case spike.
I am not commenting on the current proposals or decisions, just pointing out that there are more applications that can use low latency.
