You can still use it in ZMQ 2.2 but you won't be able to upgrade such
apps to later versions.

Anyhow there are better ways to do this (which is why few people
stressed when we removed the feature).

If you really want persistent subscriptions you need explicit
management and acknowledgments, and I'd do this using a ROUTER
publisher to DEALER subscribers.
