Don't kid yourself. This is wishing for a security outcome which will
never reach fruition because of asymmetric interests and capabilities.

I find that $CLIENTNAME or some other stand in for the client is a potential

The PUBLIC DNS is not secure against eavesdropping or parallel
construction and never will be. Just like the destruction of whois (never
was a good tool) doesn't prevent reconstruction of people's networks.
People like me get paid a lot of money to see that this is so, and at
least in some cases I remain convinced it's a good enough idea I don't
care what people think about it. I even offer software to accomplish this
for free on the internet; I even leverage features of e.g. BIND to do
this.
I can make arguments for being generic, or provider centric, or customer
centric; I can also make arguments for outright lying. Hey, choose your
own adventure; other people will judge you accordingly.
