Yup, I’ve always considered my private/personal domains something akin to interfaces in programming. Send messages here, and I’ll receive them. Despite changing the email providers and services several times behind-the-scenes. The people contacting me need not worry about the details, they just want to contact me with some amount of guarantee that the address is valid, and with no need for unnecessary questions as to whether or not it might have changed. It hasn’t and it won’t, worry not.
