In my own implementation I wrote a queue system to force message ordering and support offline messaging state and so forth. Control frames can be sent at any time irrespective of message ordering without problems, however. In the end an in house implementation that allows custom extensions is worth far more than any irrational unfounded fears. If in the future it doesn’t work then just fix the current approach to account for those future issues. In the meantime I can do things nobody else can because I have something nobody else is willing to write. What’s interesting is that this entire thread is about performance concerns. If you raise a solution that people find unfamiliar all the fear and hostility comes out. To me such contrary behavior suggests performance, in general, isn’t a valid concern to most developers in comparison to comfort.
