One snag is that if they are temporary, it will inevitably lead to "returns"
that don't happen, and the original and new "owners" both using the prefix,
which will cause confusion/ambiguity/lack of uniqueness, which is thus breaking
the original goal of the draft.   There's enough under the /7 to not need to 
have temporary allocations.
