It is similar to ECN indeed.  In both cases, people changed the
specification, and complained loudly when their changes are
incompatible with the installation base.

In fact, the problem with NODATA responses is that it is rather
difficult for stub resolvers to tell a NODATA response from a working
recursive resolver from a “I don't provide recursive service” response
from a non-working recursive resolver.  NXDOMAIN would be unambiguous
in these situations.  It's likely one reason why most implementations
moved towards NXDOMAIN in the late 90s.
