Sorry if I appear rude. I'm just asking for a proper design discussion
on the protocol, which should IMO solve problems specific to the
protocol, and not layers above or below. Specifically, TCP in this

The lack of such a discussion has, I think we realize now, crippled
our ability to introduce new features experimentally in 0MQ. I'm
hoping a proper design discussion that focuses on realistic goals will
lead to a proper and backwards-compatible evolution of ZMTP.
