The reason why the second interpretation could be argued to be useful is if
you see the exchange as:

Client: I propose a max.packet size of 128 MB.
Server: That looks a bit large to me, how about 64kB?

So the client is advertising what it's prepared to accept as a maximum, and
the server is either confirming it or saying it'd prefer a bit less, an
exchange a bit like some of the cipher suite-type negotiation.
