Perhaps, or in a lot of cases, the web hosting provider gives the customer the
DNS records to copy and paste into their DNS provider's console.

This tells us that in practice, any sort of complex master file format is
a waste of effort.  If the users are going to copy and paste, they might
as well copy a base64 blob and not worry about making it easy to read.

The wire format can be the same as what it is now.
