Perhaps, but that would take years to roll out - also, if it's moved,
then 301 or 307 (or 200 OK, with "we trashed this page, gasp!"). If a
user wants to find a 404 page, then they can manually go to a Web
Archive to find the page.

The Firefox extension is just helping with that step: the point is to
revive the page despite (in spite of?) what the server wants - the
extension and the user don't care and are in fact, directly trying to
subvert the server on purpose (by design).

Thus, it seems like a waste of time to work around this with new
codes, when the old ones are suitable - and it would just start a
small arms race against web archives and extensions that facilitate
finding lost content.
