It depends on the wiki. Suppose, for instance, you're a RationalWiki user
editing Conservapedia, and then the Conservapedia sysops decide, "Hey wait,
this user is a troll, so let's block him and delete all this work." If he
asks for copies of his articles, they might say, "We don't want to help you
spread that nonsense any further."
There also have been wikis whose databases got corrupted, and then they
found out that their backups weren't usable either.

Sysops can view all deleted revisions. But when problem with wiki's HDD is
still a problem.
Then backup, backup, backup is a solution.
Yeah, this is from the administrator's point of view, not the user's one.
But I can't see any reason why such extension would be useful still.
As a sysop of cs.wiki I personally have no problem with sending the content
or restoring it when there is some reason for it. Yeah, you may say not
everybody know that the content could be restored technically. But those
who know they may use such extension would know the content can be restored
too.
So instead of thinking about the extension itself I would rather talk about
the need for it.
Best,
