I have no doubt that someone would complain about it, but I think it's better than the alternative.
Determining if changing any function will cause an index to break is not a straight-forward problem. I don't believe that PG right now keeps a graph of which functions call which, so replacing a function deep in the logical calling hierarchy could break the index as easily as one mentioned at the top.
Yes, I can see that would indeed be a problem. Are there future plans to start tracking such dependencies? It seems like it would be a good idea in general.
