I'd prefer to get rid of this functionality altogether. It's wrong
even in cases where people aren't being malicious.
Example:
I have a document that represents how many things I've got.
On node A, I increment the number of things. I go from 5 things to 6
things.
On node B, I increment the number of things. I go from 5 things to 6
things.
Replication catches up, sees the same digest, and now I have six things
-- but this is incorrect. I have seven things (or at least a conflict).
This does will happen with any hash, but no UUID.
