I know they were killed off in regular 40K, but do people still use the Squats in Epic Space marine/ Adeptus Titanicus any more?

I have seen lots of miniatures on EBay, and other sites. It is a wonder that they are not still useable by fans of the game. I know GW would never openly support Squats on their website, and with the current set of army lists they publish. Can the current set of rules be used with the old Squad cards, and Squat lists to build an army that you can use?
