All of your reasons make sense to me, it's just that all the advocacy docs set ZMQ up to be this game-changing system. I can totally buy "a fairly simple wrapper about sockets that makes life easier for me." "world-saving superheros of the networking world" not so much.
I don't know, the simple building blocks it provides can be combined in a bunch of ways that are really pretty cool. I think apenwarr would might call it a "simplifying assumption". It's hardly ever the complex things that are game-changing, right?
