Agreed. This isn't a video game, where undocumented "easter eggs" are fun to discover. It's supposed to be an enterprise-level toolkit for managing data.

Imagine if you bought a toolkit from, for example, Sears, and it had some tools in it that you had never seen before. So you ask them what the tools are and how to use them, and the answer given is, "those are undocumented by design". The reaction? ... Yeah.

Now imagine that periodically, those tools automatically do things inside your toolkit. You don't know what, and are told to bug off if you ask the manufacturer. Kind of creepy, right? I mean, you could probably use that in some sort of C-grade horror flick (filmed on a WalMart video camera that has buttons on it that the manual tells you are "undocumented, use at own risk").

So, yeah, document this stuff. That's my take on it.
