I'm subscribed to the kde-devel mailinglist and there is a rumble going on because Mosfet has removed all his "non-important" styles from the cvs-tree. He is pissed off about something. People from KDE are trying to pursuede him in putting them back, but so far no luck. So if things won't go well we will not see Liquid in KDE and maybe not even most of the other cool styles in there from mosfet. I myself hope mosfet will change his mind.
I've been on that list a couple of years and IMHO Mosfet is a fiery character who takes things very personally. He'll probably calm down, although whether he'll put his code back in I don't know. Doesn't look like it at the moment. It's not a great issue though. As he says himself, there's plenty of scope for having his own development CVS which distributors like SuSE can take code from. It just means a bit more work for SuSE, plus a risk that I18N isn't going to get done.
