Oh, thank heaven.

I don't like very many of Wikia's choices nowadays (okay, actually, in truth some sound pretty okay) but this one is at least neutral, if not positive, presuming the testing during transition is thorough.

(Sad that this probably still means no Monobook, though. PseudoMonobook is good for resolving about 70% of my issues with the default skin but it's still not Monobook.)
