I would favor the simplest and most consistent solutions to these
problems:
1. If it would cause stalemate, the wormhole is not formed.
2. If a promotion square is a wormhole, the pawn passes through without
promoting. It does not regain its double move.
3. If it would put the King in check, the wormhole is not removed.
