There is already. NIP-08, I think.

I parse mentions already just can't write them
Would you be interested in using our API (nostrplebs.com) to allow users to register a NIP-05 ID from one of our domains, directly from your client? A portion of the registration fee would go to you, the client owner, to help fund your development. Let me know! Either way, keep building! It's looking great.
Tell me more, I wanted to also offer something like this directly on snort domain but a drop down with multiple options would be cool
I think adding your own domain is great. It allows people to represent their client and helps spread name recognition for you. However, maybe this could compliment that by giving users additional choices and options to pick something that fits their identity. #[4] may be able to talk more about the backend, but we have the API and accounting already in place to be able to offer this service to clients and pay them accordingly.
