Looks like a good default policy to me.
So there always is at least one IPv6 prefix (if not a GUA, generate a ULA).

It still provides always-on IPv6 connectivity. And would therefore simplify protocol design and implementation.

Does it seems like a better compromise to you (Mikael, Erik, Wuyts) ?
