In the the end Jeff Bonwick himself came in and stated that this was something he was working on, and it seems like this work is finally making its way towards Opensolaris with PSARC 2009/479 being discussed at this weeks ARC meeting (BugID 6667683). This change will make it possible to revert back to the last TXG if the pool is in a inconsistent state by using the new "-F" flag to zpool. I've myself never encountered this problem, but it's always good to have options to recover if something goes wrong. This is probably not an issue for people using ZFS in the enterprise, but if you are out of luck and are using a USB stick/driver for storing your zpool, this might come in handy.
