CheckUser is almost never given out any more to my knowledge (and despite the help doc, CheckUser is only ever used when someone is making socks to falsify consensus, vandalism/disruptive editing is pretty much not a reason).

Presumably that was made possible for wiki's suffering severe vandalism problems and was a precursor to VSTF, but most of it has passed anyway. usually, if a wiki suffers vandalism issues, they can either deal with it themselves or report to VSTF.
