This'd be awesome, and there are very few providers which offer this. When looking into this, I could only find HE and BuddyNS.

Everyone seems to be inventing their own custom API for this, which I guess is the 'modern developer friendly' approach, but it results in a bit of a mess. Example: Caddy's implementation of the Let's Encrypt / ACME dns-01 challenge has all these plugins: https://caddyserver.com/download

We ended up running our own authoritative nameservers, which is not ideal. But at least cloud offerings allow you to spread across regions.
