on that, we're trying to improve. for example, we used to forego
features that some of us found repugnant, such as nxdomain remapping /
ad insertion. since the result was that our software was less relevant
but that there was no reduction in nxdomain remapping as a result of
BIND not providing it.

To clarify that a bit...

You're saying you used to decline to include in BIND the capability to break
the Internet by returning things other than NXDOMAIN for names which do not
exist...

but now you're *ok* with breaking the internet, and BIND now does that?

If that's what you mean, I'll explain to you why that's a bad layer 10 call.

*Now*, you see, we no longer have a canonical Good Engineering Example to 
which we can point when yelling at people (and software vendors) which
*do* permit that, to say "see?  You shouldn't be doing that; it's bad."
