This sounds good if you have your wiki in English. Note that there are many wikis with such prefixes which are not any kind of an English wiki in other language. They just consider themselves to be independent, and know they have to have a prefix so the wiki has a better SEO. Is the change OK? I believe it is, there's no other way as we need to make our domains shorter. My wiki, even though it's in Polish, does not have a prefix either, so I have no reasons for worrying just like you :)
