If I understand correctly the TargetParser (invoked from the driver or the target attribute parser) will expand the dependencies of `sve2-aes` to {sve-aes, sve2} which are handled here separately. I guess that works so perhaps it's not necessary to preserve the code you are removing. At first I was worried.
