And this doesn't need to be done in a mandatory way. It can be done so that large providers can continue to use provider-aggregatable addresses. Geotop addressing is one of those 80-20 solutions where the largest 20% of providers mostly use classic IPv6 address but the other 80% of smaller multihomers use geotopologically aggregatable addresses. --Michael Dillon
