Yes -- and as a meta-comment -- using configuration management tools
(Ansible, Puppet, Chef, Salt, etc etc) makes this sort of thing *much*
easier. It;s slightly more work to setup / configure initially, but
especially if you are dealing with multiple nameservers or operating
systems, the level of abstraction you get and / or clear location for
the changes you've made makes a world of differnce.
Just like adding unittests, it initially seems like a lot of faff for
an unclear advantage (other than hipster cred), but once you've gotten
into the habit you quickly understand why it's worth it...

I don't think the execution is relevant when it was obviously a bad
idea in the first place.
This is like putting rabid weasels in your pants, and later expressing
regret at having chosen those particular rabid weasels and that pair
of pants.
