Yes. This type of behavior was what I was referring to in an earlier comment mentioning flashbacks to seeing logs from named filled with "cannot have cname and other data", and slapping my forehead asking "who keeps doing this?", in the days when editing files by hand was the norm. And then, of course having repeats of this feeling as tools were built, automations became increasingly common, and large service providers "standardized" interfaces (ostensibly to ensure correctness) allowing or even encouraging creation of bad zone configurations.

The more things change, the more things stay the same. :-)
