If that became the norm, I agree, the extra uniqueness would be desirable, perhaps to the point that you should be asking an authority for FC00::/8 space to be assigned. But then why wouldn't you just ask for a GUA at that point.Because you might want space that doesn't route on the Internet so that if your routes accidentally leak external folks still can't reach you?
That is, at best, a false sense of security which is worse than no security. Owen
