i think the .id.au domain licensing rules are a pretty reasonable middle-ground:

The id.au domain name you choose must match or be an acronym or abbreviation of your first name or family name, or your nickname

you have to provide ID to register any .au, so you’re verified as a person, and though they don’t pre-check your nickname, AFAIK if there’s a complaint you do have to prove that you’re “known by” that name
