The significant problem with long-lived domain registrations is not the price, but the potential that people tend to forget about the renewal date, move email address and credit card number over that 10 year period, and lose the domain when it comes to renewal time. If you're talking "forever", or at least a lifetime, a 10 year cliff is a long time but not that long. You could do things, like actually turn off the domain service after 9.5 years, giving people a 6 month retention reminder of the blunt sort, but there's not much clever that I can think of.
