I suppose this is because cpuset's offer some middle ground between 
collecting data per-cpu
vs. collecting it for all cpus ?

What happens when someone is using cpusets on such a machine and changes

in response to other needs. All taskstats users would need to monitor 
for such changes and
adjust their processing....seems like unnecessary tying up of two 
unrelated concepts.
