That is another possible API. Though the way to do it is probably just to add
a socket option ZMQ_THREAD_SAFE so all the existing socket types had
a thread safe variant. Alternatively

	ctx.thread_safe_socket (ZMQ_PUB)

would do the same thing. The "per socket" thread safety has the advantage of
providing more fine grained control. But that's also a disadvantage (lack
of enforcement requires more code review).

In all these cases the safety is fully upwards compatible. The changes provide
new features, nothing old breaks.
