Yes, communities may lapse into inactivity on account of any number of reasons, and yes, vandals may show up and disturb unmonitored content, but if you forbid potential good faith contributors from making positive changes, you might as well just remove the wiki altogether. There is always room for improvement on any wiki, even those dedicated to niche subjects. Well, maybe my statement is too rough. A wiki of normal operation often needs an admin team that is able to remove abnormabilities in time, or vandal can easily undo their efforts.

Perhaps, the last admin of a wiki can resign and retain the wiki (just ignore about being closed) with this function until another one who is willing to adopt the wiki. It's like "preserve a wiki".
