No, not really.

Sure, but that’s the absolute worst case and it only remains true if he
has managed to inefficiently use every single /24 in his entire address block.

It would probably depend on which pieces, but Owen is unusually obese and so
probably has more tissue than the average person he would be willing to part
with. Nonetheless, your point is made. However, see above… Using the absolute
worst possible case of the worst possible choices made in the past is probably
similarly atypical as an exemplar.

But that’s also not likely to be the case.

I suspect that at this time, the community is unlikely to come to
a sufficient consensus in either direction and thus the existing
language remains despite multiple attempts to change it in either

So you want it to be optional for ARIN to work with the resource holder,
but the resource holder is still required to return the space under section
12 and other parts of section 4? I am confused by this desire.

Not the way you worded it, but at least now I understand your actual
intent. You’ll need to hack up a lot more of the NRPM than 8.2 to achieve
that desired result.
