Yes, I would like to see pipelining addressed in the spec. Right now it is
unclear if this technique is legal. The spec does not forbid it, but I don't
think that is enough, is it?
I'm also not sure what parts of XMPP could be declared as pipelinable.
Certainly the opening <stream> exchange, but I don't know if the rest can be
done this way, given the asynchronous nature of elements exchanged in the XML
