Yes, that's a great issue here, exactly what i tryed to implemented since. With bitboards as always it was a great fun to implement some heuristics with king in extended center and a lot of queen and rook attacks and no or less (eg. only one queen or rook) defenders (except the king of course) around. Also considering queen/rook dominated areas on one side near the exposed king on the inner 16 squares, eg. two neighboared (rather) open files or ranks, with a lot safe check possibilities.
