I think in case 1 it would leave unread stuff on the wire that would confuse the next reader;
in case 2 you'd get an end-of-stream type of exception.

A subclass is OK, because it does not change the existing filter class, so only if somebody
used the new class before fully upgrading the cluster (and client) would there be a problem.
