I am not saying that we should not do DNS over TCP. It's in the RFCs. 
But there is a cost on doing traffic over TCP compared to UDP and that 
is the case even if we only consider normal and not DDOS traffic. I'm 
not sure if TCPs role will get significantly bigger over time, given 
that people who operate large chunks of DNS seem to be very careful 
about avoiding it and so far EDNS has done a good job for us.

So long
