For my binding it doesn't make much difference if I am enabling/disabling functionality for 3.0 & 4.0 or 3.0 & 3.1. The logic is equivalent and only the numbers will change.

I have been watching the list for people to describe their use-cases for ZMQ_IDENTITY and I can't recall anyone really coming forward. Is there a valid use-case? If not, I don't see the point in even keeping ZMQ_IDENTITY for 3.0 (other than the fact it has already been released *with* ZMQ_IDENTITY intact so according to the rules we are now stuck with it).
