So far, I have only dabbled with IPv6, but my reading of the RFCs is that
VLSM for lengths beyond /64 is not required. Subsequently, to use anything
longer is an enormous gamble in an enterprise environment. I envision
upgrading code one day and finding that your /127 isn't supported any more
and they forgot to mention it. I'll stick to /64, though it does seem a
horrible waste of space.

Someone else might have read the RFC differently though.
