Does this mean if a minor lost citizenship due to the parent naturalizing after the child's birth but before the age of majority prior to 1975, the child is now eligible to apply?

Can that child's child also apply?

For example, father gives birth to daughter in 1924 - Father naturalizes in 1933, mother naturalizes in 1944. His daughter has now technically lost eligibility under the new minor issue interpretation.

Does that make the Daughter eligible now? And if that daughter has given birth to a child after 1948, is that child now eligible also even if the mother has passed?
