You don't really have to worry about squatters.

As for the XML database dump, it might not be available anymore. It's usually only saved up until a month after deletion, if at all.

Also, regarding the url: deleted wikis are still visible in Special:UserActivity, so have you checked that? However, if you only have Discussions contributions, it's not visible.
