That's not universally true. If you operate a highly efficient backbone network, you actually get greatest efficiency from accepting your traffic on a hot potato basis and controlling it across your own network as soon as possible. Advertising a single global prefix facilitates that quite well.

The backbone operator should have the choice and this proposal accomplishes exactly that... Either number your global network out of a single RIR (mostly) or number your network out of each region (mostly) with room for some flexibility to accommodate the differences between theoretical optimizations and real world deployments.
