NAK. If we have disconnect messages (NBD_OPT_ABORT and NBD_CMD_DISC), it
makes sense to say that clients should use them. Protocol violations by
peers are a different matter; but in the general case you should drop a
connection properly, i.e., by using the relevant "close the connection"
command.

(I realize I didn't comment on this earlier, but I changed my mind
during the discussion about DISC).
