This also occurs when dealing with channel-level protocol exceptions, so this behavior is doubly important to get right. I think one of the hard parts here is that the client needs to be aware of these events in order to ensure that application level consistency requirements are being kept. The other part is that most of the client libraries I have seen are very imperative. It's much easier to handle retries at the library level when the client has specified what structures need to be declared again during a reconnect/channel-recreation.
