Just for starters, a 40XXX error report will fail to provide the
duplicated key's value. This will be a functional regression,
on top of breaking existing code.
I think an appropriate response to these complaints is to fix the
documentation to point out that duplicate-key violations may also
be worthy of retries. (I sort of thought it did already, actually,
but I see no mention of the issue in chapter 13.)
