Hi Mike,

I can't think of any persuasive use cases. If your original data fits in
memory, then there is little reason to make a snapshot copy of it, you
might as well use the original. The point about snapshot is that it is
designed to capture the content of a node and its immediate "relatives"
(the ones you are most likely to need access to) without the memory
overhead of holding the whole document; so it's all about memory use.

I guess there could be cases where the output of snapshot() happens to be
exactly the data that you want to put into a serialized message and send to
some other system, but it's more likely in general that you would want to
control the message content more precisely than this.
