Cloudflare automatically adds the required CAA records for Universal SSL right now (without showing them in the UI), but it might be a bit concerning for some users to see these unrecognized CAA records in other tools/sites.
@prajaybasu thank you for making this suggestion. We are aware of this issue and working internally to come up with a solution. At the moment, the best way to prevent this from happening is to disable the Universal SSL from the dashboard before pointing to Cloudflare’s nameserver for a new zone.
I don’t think the suggestion is to prevent anything. On the contrary, I think it’s good that CAA is added as a result of Universal SSL.
One solution, like the suggestion suggests, could be to add a view-only record that displays the CAA. Possibly even toggleable from the advanced options.
