This is a big opportunity for registrars to make their customers feel safer: "We will go to extra lengths to make sure you don't lose your domain this way. We will pick up the phone and call you."
"And in order for our thin margin business to be able to provide this new service we've opted you into, we've increased your registration fee by 50%. Don't thank us, thank the friendly folks at domain-admin@icann.org"
(in all seriousness, I expect the high end registrars probably will do this. Shame they're apparently not permitted to exercise discretion and not kill your website that nobody has objected to)
Yeah, like I need my registrar calling me all the time. What if you have several hundred domains? Are you really going to call and harass me about each one?
Sure, but you always have a few Truly Important domains, that you DO NOT want to lose. This is about those. An easy solution would be to charge you a few bucks more for domains you designate as Important.
No more than they would send you several hundred separate bills. If all the domains are linked to the same account, verify the account and you're done.
