data plane speeds are measured in terabits/sec.  Control plane capacity 
for dealing with punted packets is measured in kilobits.  As end user 
and data plane speeds increase, rate-limiting for problematic packets 
will tend towards towards 100% loss.

It doesn't matter if your packet stream is subject to 20% loss, or 100%, 
or 100% for 20% of the time - beyond a certain point, the end user 
experience will languish in an indistinguishable morass of unusability.
