The exact behaviour of PowerDNS came about after I asked the DNS RFC authors
and IETF people how we should handle out of bailiwick CNAMEs. It does not
cause problems and is exactly what the RFCs require. So you are seeing a
non-problem.
If you really hate the SERVFAIL you can enable 'send-root-referral' and
PowerDNS will send out a useless root referral that mostly means the same in
this case, except that it wastes bandwidth.
Good luck!
