Well I used to use http://dev.bukkit.org/server-mods/vchest/ on my old server and just starting one back up and this is way outdated will someone update it for the public so many people relied on it
I'm familiar with it's code and I don't see anything that would break on updates such as NMS calls. So I would say don't worry about it. If there is an issue, then I know that the is active on bukkitdev.
