That sounds good to me. Please keep in mind that not all clients might want to take advantage of these things as they might have their own fuzz-match logic and external result injection.

A wider configuration space means testing is more work, but happy to live with it. What do you think?

I'd be ok with off by default, as long as it's possible to turn it on :)
