Operationally, the testing should stop prior to allocations
from the block, regardless of size. I think it's a binary
question, they're either in production or not, and if they are,
there should be no intrusive testing.
It looks like they were given real ARIN allocations for those test
prefixes, so its not like those blocks are going to assigned to some
random network who goes to use them and finds out there is a Cymru
announcement on their space.
