Insanity?
Using IPv6 by default can lead to suboptimal results, but there's
really no alternative: even in the IETF people think I'm a few bits
short of a /128 when I talk about running IPv6-only. And as long as
you have both IPv4 and IPv6 connectivity and prefer IPv4, you're
never going to see if IPv6 even works, let alone how well.

Believe it or not, there are already products that do IPv6 NAT.
