There are lots of pathological ways to increase processing cost ó e.g., 1-byte DATA frames. Weíre not talking about limiting those (and I will be EXTREMELY unsympathetic to anyone who brings it up after this).

Complexity has many facets, as weíve heard; itís not a clean-cut decision. 

AIUI the DoS scenario had more to do with HOL blocking and cost of teardown; if thereís a DoS vector thatís specific to this scenario, letís hear it.
