[policy-wg] IPv6 PI policy

I've been looking at this, and Jordi states that the current policy is
to filter <= /32, I actually disagree with this.
I've been looking around at various route servers, and checking various
networks, as well as speaking to a *LOT* of network admins, currently
the actual ACTIVE practice is to filter <= /48, I have yet to actually
find anyone who is filtering on a <= /32 basis. While I'm sure they may
exist, if they do they are in my opinion probably the vast minority.
Again I reiterate, P.I space of /48 with an option for /44 upon serious
Other than that, I support the policy
