Terraform and OctoDNS can make this easy.

Never let the UI of your vendor be the source of truth for your DNS setup.

If you have the zones in code then updates should be easy to distribute to multiple vendors.

Also: given the nature of DNS caching you will have to roll changes in a way that is compatible with temporary inconsistency anyway.

I have seen such a setup once and it was a life saver. People recommending that are right. People fearing the complexity are also right. Be careful to have good tooling.
