Agreed that the cue would be late in the game, just another subtle clue earlier rather than having the "oh crap, this isn't looking right" in the last 200'. The did ask the question about being cleared to land, they appear to have doubts about the picture not looking right. Having the ILS up would have instantly resolved the doubt and confirmed they were off the centreline. We get pretty good at looking at lots of pieces of information. When something like a localizer is still pegged full scale when on final, it is hard to miss.
