Yes, but for those that own/lease a single RaQ that hosts all of
their websites, it's academic since if this server goes down you
cease to exist. Having secondary DNS on a separate server won't
remedy this scenario in the least.

I've yet to experience any noticeable performance loss by running
DNS on my RaQ3/3is. I would have to say that the amount of processor
cycles DNS consumes is fractional, at best.

That's very admirable, but again, if the customer only has a single
RaQ, and less than a hundred clients, secondary DNS is a mute point.

Again, this is an ideal setup and I commend you - but you probably
have more than one server and hundreds (or thousands) or clients.
We are talking about a single RaQ3 here...
