But castling rules aren't required to play FRC. In fact, every game of chess is
a game of FRC, is it not?

All engines may not *support* FRC castling, but they can play it legally.

>Chess Engine *__and__* Chess GUI must support FRC rules.

This is not true. An engine that can play legal chess and supports the Winboard
or UCI protocol may play 100% legal FRC. Only the GUI must support it. The
engine that doesn't understand the FRC castling can still play legal FRC, but it
will be at a disadvantage because it will not play or suspect castling moves. I
bet that Ruffian would still beat any of the three engines that support FRC
castling.

Think of it another way if you'd like. Castling is a part of regular chess, but
it is not required. If two people play a game of chess, and neither player
castles, it is still a legal game of chess. The same holds true for FRC. If two
engines play FRC and neither engine castles, it is still a legal game of FRC
(and not shuffle chess), because FRC still has rules that are different from
shuffle chess IIRC (bishops can't be on the same colored squares for example).
