do.

although the IP address block becomes damaged goods, as there
are more than a few ISPs that will ignore any announcement that's
broken out of an aggregate. if your /24 is broken out of TWD space,
sure, people will listen, but if you've got a /21 that was given to you
by NAC, and you're not a NAC customer any more, then i somehow
suspect you'll have trouble reaching verio space, just to name one.

additionally, how is the ISP to account to ARIN for this block should
they go back for more space?

there is a widely accepted understanding of how this is all supposed
to work, and if the ex-NAC customer succeeds in gaining this TRO,
and it becomes a pattern across the industry, then everybody's
connectivity, router tables, and support budget will likely suffer.
