I don't see a way to fix this issue without introducing a new callback.
And frankly I don't quite understand your concern. If the new callback
proves to be useless / harmful for transaction DDL, we will remove it -
after all engine API isn't carved in stone.

Because the space becomes invalid before it gets destroyed - ALTER moves
indexes to the new space before writing to WAL.
