This I agree with.

This I do not. There is no such thing as "legacy" addresses. ARIN
policy covers all resources in this region, any exception that could
possibly be argued for is temporal. So, in the strongest case,
"legacy" is a historical status that can not be renewed (hence the
name, I guess).
