No it doesnt make more sense. Having nanomachines specifically go into gonads and change dna there for no reason is stupid. It only opens companies for getting sued for adding a dangerous nonsensical features.
Nanomachines already making all alteration of DNa...weird. Sicne their can change PC arm or leg why it can;t go into gonads to change them? Ofc heir can and it all only comming down to one thing: programming them to do specific thing.
So I take for sake of sanity Fen&Co set that none of existing TF items got nanits that would target DNA in host gonads. Even all those "illegal" items still seesm to avoiding touching gonads dna. Well aside that actualy their would need to affect already produced reproductionary cells since simply modifying dna of cless that still are before meiosis will still carry unpredictable factor.
