With current addressing scheme we only have 2^13 times more site addresses than IPv4, which is plenty in absolute numbers, but not necessarily enough for more coarse aggregation, and definitely not infinitely future proof. Crucially though, if we change it, we just have to change how addresses are allocated, not change the protocol again. |

Yup, and only less than an eighth of the total IPv6 address space has been allocated [0] [1], so there's still plenty of room to expand, even if we have to throw every current address out and start from scratch.
