I have had my firstname lastname domain (.dk as I am danish) since 2001 and have never seen a website refusing my domain or refuse to send a password reset. I also have not had issues with giving the address to a non-technical person, only issue I have had is that the risk of spelling mistakes are higher than @gmail.com
