Too easy to exploit. Not personally interested.

Righto. Thanks.

A fine idea in theory, but we definitely like to retain control over the availability of a lot of keys in the game. While I imagine it would be possible to tag certain keys as uncopyable, there's such a large list of them that it would be a PITA to sort.
