ZMQ's default behavior (and in some cases only behavior) of dropping new messages when buffers are full, made it a no-go for my client. We ended up switching away from ZMQ to a more traditional durable queue and ended up saving a ton of code complexity and got a lot of reliability in the process. Having now researched it I can't think of a reason I'd ever use ZMQ again. I'll either use a durable queue when I care about message delivery, or something much more traditional when I don't.
