Will reverting DNS wildcard have any adverse affects?

I keep trying to think of how this discussion could be operationally relevant. The only thing I could come up with is: Will reverting back to the proper NXDOMAIN break anything? I have only seen inconveniences on my network since they changed, though I know some had it worse than I did. For the benefit of other NANOG readers, make sure reverting back won't cause more headaches on your network. Gerald Coon - How are ya? Never been better, ... Just once I'd like to be better.
