Are there any recent statistics about SUL? How many accounts exist on Wikimedia projects, how many accounts are SUL, how many unconflicting non-SUL accounts remain, how many conflicts remain? How many Wikimedia projects participate in SUL and how many and which are not part of it?
All Wikimedia projects are part of SUL now. The wikis under WMF control that are not on it are either private wikis or sandbox wikis.
