let's suppose I just happen to have, or have access to, a botnet comprised of (tens of) millions of random hosts

DNS reflection/amplification attacks aren't intended as attacks against the DNS, per se; they're intended to crush 
any/all targeted servers and/or fill transit pipes.

To be more clear, the point of DNS reflection attacks is to amplify the amount of bandwidth the botnet can muster 
(and perhaps hide the true source).

If you have 10s of millions of bots, you don't need to amplify. You can crush any single IP address on the 'Net.
