I realize there is a -01 version of this draft.  Nonetheless, this
comment still applies.

One of the major stumbling blocks in managing control plane filtering
in my experience has been when a platform lacks sufficient diagnostic
capability such as control plane filter logging.  Perhaps some mention
of this in the Design Trade-offs section might include some text
highlighting this concern.  Rate limiting can be particularly
troublesome when "bad" traffic starves the "good".
