Hi Nemo. It is a great idea, but it needs a lot of resources (space and bandwidth).
By the way, MediaWiki includes dumpBackup.php to make wiki backups. But people do not use it, and do not publish backups. If we make an extension or feature (disabled by deault), it is the same problem. Only a few persons are going to care about enable it and publishing backups.
Well, apart from the central repository, it could even be enabled by default if the wiki is under a free license, given that dumps of small wikis are so small after compression.
