Okay, that seems reasonable to me. If folks who need to multihome in
v6 never bust holes in the ISP /32's then filters can be applied at
/32 in the space assigned to service providers so that TE doesn't
contribute to a DFZ size problem.

Can this be forwarded as a suggestion to the AC as they deliberate on
2007-21 or would we need to make a new proposal?
