I've been through this twice this year where a reasonably large non-tech business came to me saying requesting help, only to find the credentials for their domain left with some previous employee and the "password reset" emails went to some @hotmail.com address noone knew how to access. Businesses see that sort of thing as normal and expect you'll just call the registrar and have it sorted it out. I absolutely cringe at how easy it's always been for me, but I likewise think anything like you've described would be just end up with an awful lot of businesses locked out of their domains.
