Well, it's not actually as bad as that.

The packet limits seen in the DNS proxies in the CPE are likely to be a 
problem if you're doing your own validation, but if you're relying on your 
upstream recursive resolver to perform validation for you then you should 
be fine.

The main exception to that are those few routers we found which failed to 
support DO=1 or AD=1.
