A Warning: header code would meet all these fine-tuning requirements
and would also be effective on any status code.

IMHO, the non-permanent aspect Julien pointed out is a stronger reason
for allocating a new status. To create a symmetrical non-permanent
non-erasing form of 410.

I am sure that the entities behind the related laws would greatly
desire the 410's ability to automatically disconnect other content
(links references, bookmarks, history records) from mentioning a
non-legal resource.

I would like to see the draft outline the alternatives that have been
considered and reasons for their rejection. That would help in any
future attempts to improve things further.
