It's quite easy to program castling in Chess 960. Why is this still not implemented?

Wikipedia does not explain why Queen Alice does not have castling in Chess 960.

LOL ... you must not be a programmer, ernesto_che. ;-)

Castling in Chess960 is not significantly harder to program than regular castling. The only difficulty is that, if the king is on the b, d or f file and is moved to the c, c or g file, respectively, the program may have to ask the user if they're castling.

It is significantly more costly in terms of code lines. There are times that pieces don't even move. You have gone from two almost identical possible moves to a large number of moves with significant variety. Especially when code lines are at a premium such as in this case, the overhead needs to be factored in. For stand-alone software, it is reasonably trivial.

Is Chess960 even supported on this site??? ?:-(
