It's an information leak if you can tell the originating node because
of the uuid. If we want an option to flag docs with information about
the originating node, we should add that. Also, the isn't the
right place for this, as what you want to know is the origination of
updates, not documents.

UUIDs that are consistent per-node are bad not just because you could
trace the node. There is even information leakage if you can tell that
a set of documents originated on the same node.
