Exact amount or more, technically. Strangely enough, the community
came to consensus around the idea of allowing someone to sell off
pieces of their netblock without limitations on the fragmentation, but,
each recipient is supposed to only get a single chunk.

I'd appreciate it if staff can provide words that would do that. It is my
reading of the language in 153 that it says exactly that. Since it sounds
like staff has a different reading, I think I have made the intent clear
and will instead request that staff provide language that will have
the desired effect.
