Typically, those who have "default route only" are too small to be 
heard,
and their "wishes" doesn't go beyond the first line of support.
Not to mention that it does not work at all if upstream is a monopoly,
especially a state monopoly, who wont move a finger for "optional

All Tier-1 implemented it? No.
Major hosting operators, such as AWS, gcloud, etc? - No.
