It still doesn't help with the gaping plot hole of them not actually being fucking stuck
Just rewatched it, and if it helps I think it can bear out my take, which is that the paradox isn't so much supposed to be
"Amy and Rory end up in New York in 1938, and the temporal lines are too mixed up to retrieve them from specifically that point in time and space"
but something like
"Amy and Rory end up in New York in 1938, and live out their lives in the past, and the Doctor knows that's what happened because of the book and the gravestone, and can't change or even approach that fixed point without a temporal disaster that's a smaller-scale version of what happened in The Wedding of River Song"
Of course (as with what happened to Rose and Donna) it's also nicely set up so that it could be got around if the cast members concerned ever change their mind -- by making the appearances roughly the same while not actually changing time quite as badly as the fixed point not happening at all, again as with TWoRS. This new scene would made that harder, but since it's unfilmed it doesn't necessarily count, right?
