From now on, will there never be a "Hibernate" feature in Ubuntu again (since it was known to contribute to data loss), or is the removal of the "hibernate" option only a temporary measure until the data loss issues are fixed? I find that it's easy to lose data now that the hibernate feature is gone and suspending the OS is the only option; will it be like this forever from 12.04 onward?

Hibernate is still there in 12.04, it's just disabled by default. See How to enable hibernation in 12.04? for how to enable it.
I don't know about the future plans but I guess it will stay this way unless it works reliable. In in the current version of 12.10 it's still disabled by default.
