Breakouts done from PA space is normal in ARIN-land, but it's less common 
in RIPE land for instance.

We need to make sure renumbering is easy, otherwise we're going to see 
more and more entries going into the DFZ BGP table. The /24 boundary and 
IPv4 scarcity was a natural hindrance for this in IPv4, we need to create 
equal "hindrance" for de-aggregation in IPv6 otherwise I fear that we're 
going to sit with millions of routes in IPv6 DFZ in 10-20 years.

Unless of course this is a cheaper way of handling things than making 
renumbering possible.
