I am seeing the same here. We mostly use /64 as p2p links in 30071, and
also have /127's and /126's and even some /112's with legacy peers.
No problems exhibited in all cases.

But that still doesn't change the fact that /64 is recommended minimum
subnet size. :) Then again IPv6 gives us lot of *subnets* before we even
talk about gazillion amount of hosts ;)
