Going back to Ben's original problem, one tool that Freebase used to help manage the problem of incompatible type merges was a set of curated sets of incompatible types [5] which was used by the merge tools to warn users that the merge they were proposing probably wasn't a good idea. People could ignore the warning in the Freebase implementation, but Wikidata could make it a hard restriction or just a warning.

I think that this idea is a good one. The incompatibility information could be added to classes in the form of "this class is disjoint from that other class". Tools would then be able to look for this information and produce warnings or even have stronger reactions to proposed merging.
I'm not sure that using P1889 "different from" is going to be adequate. What links would be needed? Just between a gene and its protein? That wouldn't catch merging a gene and a related protein. Between all genes and all proteins? It seems to me that this is better handled at the class level.
