This is not true. You can only unlock trades by using the last trade in their trade list. So if the last trade in their list is broken via that bug (e.g., the first Seneca farmer villager), then you cannot ever unlock any other locked trades and all the effort put into unlocking that villager is wasted.

How do I make a soufflé in space?

If putting them behind doors is meant to be for grief protection, then they are very different. Right now any attempt to grief an iron grinder is logged and can be rolled back. With villagers, it is possible to grief them in a way that is NOT logged (via exploiting that Mojang bug I mentioned earlier), and even if the grief were logged (e.g. killing the villager) there is currently no way to undo the grief. If you wanted to lock an iron grinder just to make it private so nobody but you could use it, that might warrant its own thread.

Sorry things got a little off-topic. So as I understand it now, we have to (and should) put our villagers behind locked doors if we want to protect them from grief/bricking?

Hm, my gut it telling me that the "owned" definition used in the rules is outdated. It's probably from before rev10 when we didn't have a way of tracking mob kills. Back then you DID need to region-protect mobs if you wanted them to be rolled back (usually by placing a redstone torch by an iron door protecting them). I very much doubt that one could go around killing farm animals that are not hidden behind an iron door and claim that you were not technically griefing. Villagers definitely seem like something which should be open to the public. It wouldn't make sense to require individuals to require their own villagers if they would like to trade. I'm hoping we could come up with some sort of grief protection apart from "you can't trade with these villagers, get your own"

Currently if a villager is griefed, the best we can do is replace it with a new villager. While this works very well with farm animals, I don't think this is sufficient for villagers. Villagers require you to unlock their trades, and a fully unlocked villager represents TONS of trading, time, and resources. None of that can be rolled back atm. Also it is possible to "brick" a villager so that their trades are permanently locked, rendering them useless (See https://mojang.atlassian.net/browse/MC-749). This way it is possible to grief villagers in such a way that we are unable to determine who the griefer was. Ideally we would back up a villagers trade list, and be able to create a new villager with that trade list in the event of grief. Is this something that we could do? Or would we need to make villagers a private resource (like farm animals in rev9) in order to protect against grief?
