Sounds like this should be a feature request somewhere.
The are many DNS providers that don’t have plugins ported for Certbot. And there are many providers that don’t provide an API so their clients can have control of their domain properties.
There are other ways to obtain Lets Encrypt Certificates other than DNS auth.
@_az has discussed this before DNS providers who easily integrate with Let’s Encrypt DNS validation
It would be worth the time to take a look at it.
Hope this helps
