DNS requests and HTTP request are two totally different beasts wrt 
scaling, operation and cost. Also the current authoritative 
infrastructure we have today would not scale to resolvers on all 
clients. The OS having an resolver is a great idea until it has a 
problem, which may be the reason that a lot of OS vendors so far haven't 
done it. I do hope that the systemd people offer an option not to use
