We limit amount of bytes now, not number of packets, no?

If we limit the client, it would need to be a rate limit, otherwise it would never be able to connect again later when network conditions improve.

I'm not sure it makes sense to have a MUST limit on client, as there can be many deployments types with different attack vectors. DNS might not be in the equation. However, obviously a client should not saturate a link on connection retries.
