If upstream tends to ignore, then what's the point of making the downstream
return? Seriously.
It's in upstream's interest to ignore, as it makes it is easier for them to
qualify for another block if they don't notice they have spare.
So it seems to me that ARIN needs to do an audit on blocks returned to
upstream should upstream ask for more space.
Maybe there is a lot more space out there available for new entrants than we
think.
