In practice, many routers require the packet to go twice in the hardware if the prefix length is > 64 bits, so even though it is a total waste of space, it is not stupid to use /64 for point-to-point links and even for loopbacks!
some of us remember when we thought similarly for /24s for p2p links, especially when using rip. and consider matsuzaki-san's dos vulnerability on a /64 p2p link. the prudent operational advice today is to use a /127. randy
