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
