If there would be a need to, you simply could check, whether there are castling
rights without having involved King and Rook at traditional places or not.

It is a very bad behaviour to demand for unnecessary and redundant information.

If you create e.g. starting position 518 in Shredder (identic to traditional
chess) or any of the 18 pseudo FRC positions, there would be a difference in
such extra flags depending on a potential FRC view, without having a changed
situation at all.

My opinion is, that an engine's basic behaviour should only depend on the input
situation and not on any artificial imposed on view.
