SPDY had end-to-end 24-bits by default. As I understand it some bad
actors could and did force their large frames down unwilling
participants connections and got away with it.

The proposal is to have hop-by-hop agreement for anything other than
16KB. With bad actors receiving 431 responses, whether they be
application layer actors or h2 implementations.

Totaly different behaviour incentives, designed explicitly to encourage
a healthy HTTP/2 environment.
