Continuing on from that (and because I’m a slow thinker): that serendipity and good fortune ran out for the Prequels.
Having Ben be present at the birth of both the Skywalker children in the later ROTS film just makes him look inept, kind of sexist, or forgetful in the extreme.
Having so many other similar discrepancies, contradictions or jarring issues between the two trilogies really did damage the Prequels for so many fans back then, and in the years since.
I think Ben being present for Leia’s birth (or at least being aware of when it happened) is implied in ROTJ, and explicitly confirmed in dialogue from ROTJ that was cut from the film. In the actual film, Ben says “To protect you both from the Emperor, you were hidden from your father when you were born.” And in dialogue cut from the film, he says “So I took you to live with my brother Owen on Tatooine… and your mother took Leia to live as the daughter of Senator Organa, on Alderaan.” He then goes on to deliver an extended speech describing Leia’s life on Alderaan (all of which is cut from the movie.)
Strangely, it seems Ben never really had much faith in Leia, because in ROTJ, Ben actually says “Then the Emperor has already won. You were our only hope” after Luke says he can’t kill his father. So Ben actually repeats his belief that Luke was their only hope, even AFTER the Leia retcon is in effect. (Although Ben also says the Force is strong with Leia in additional dialogue that was cut.) It seems like Ben’s dialogue is written in a manner that is aware of the contradiction, but makes no attempt to smooth it over.
Of course, the Prequels actually show Ben present at Leia’s birth, which only highlights the issue even further (not to mention the Kenobi series).
