I haven't done any work on putting in the UA Class Variant features. If something is not included in the
Community Pack release notes, it's almost definitely not in the pack.
I'm not coding any UA. The only exception will be if it's something I personally need for my game. Once/if it gets officially published, then it belongs in the pack. I am happy to assist anyone who wants to try and code UA and will gladly put finished stuff into the pack.
