Not really, not if the limit is comparable to typical TCP send windows. A
badly behaving client can send one TCP window's worth of stuff to the
server anyway.
Specifically, the client can send
a append inbox () "01-01-2000" {9999999999999999999999999999+}
no matter whether which part of that line is forbidden, and the server has
to eat one whole TCP window before it can throw the client out.
