This is why you shouldn't combine your registrar with whatever services you have your domains pointed at. Domains should be delegated to services using a simple OAuth2 protocol. DomainConnect is technically close but very corporate and not good for self-hosted services.

Maybe i'm missing something, but why not do this using simple DNS? Nameservers at the registrar, or nameservers at some simple dns-only thing, and point hostnames to whatever you want at the moment.

The barrier to entry to using a domain name is way too high. Even just to use a domain with email you have to manually enter a bunch of DNS records. That should be a quick OAuth2 flow from your email provider that gives them a token they can use to set the records for you.
