Has it been considered to change all of the dialogue about Anakin’s saber to reflect that it’s his? For example, Maz’s line in TFA is fine: “That lightsaber belonged to Luke, and his father before him” but there are lines in TROS that call it Luke’s when it’s, well, not. Luke built his own. For example, when Rey tells Leia “I will earn your brother’s saber” could brother somehow be replaced with father?
Luke owned it for two films while Anakin only had it for one. It was definitely Luke’s just as it was Anakin’s before that.
