The prequels showing how Anakin becomes Vader make for an interesting case of dramatic irony in the classical mold. I don’t think it’s necessarily a bad thing at all.
I do think it would be cool if, instead of Anakin having literalistic visions of Padmé dying in childbirth, he had more symbolic ones of suited Darth Vader striking her down. That way, first-time viewers watching chronologically would get a reveal of their own, comparable to that of “I am your father” from watching in release order.
