I would say keep in mind that I've observed them transforming SERVFAIL situations into NOERROR for AAAA, so while they may be 'OK' for a browser, they certainly aren't good for SMTP or other application uses.

Take a look at the data posted last week, they were least likely to return an error (which is good for the user) but with perhaps dubious benefit.  I think it's also fairly well known that these things (can) cause poor performance of CDNs if you are not using a local resolver.
