How do you extract the TOC at all? There are no tools for manipulating
the TOC that I know of, and I'm not sure we should provide any. It's not
documented, it's a purely internal artefact. The closest thing we have
to being able to manipulate it is --list/--use-list, and those are
useless for this purpose. So this method description does not compute
for me either.

+1 for providing a way to restore an object to a different object name.
